Well... Where to begin.
I'm a girl; I suppose that's as good a place as any. And I'm from the US, though you probably already knew that from the flag next to the dates. That's about all the specifics worth mentioning, I guess. (If you were one of the many people who told me never to give away my name, age, address, or phone number over the Internet while I was in school, you can relax. Good job.)
Anyway, I've always been a bit of a bookworm and enjoyed making up stories of my own, especially when something would happen in a story that I didn't like and I'd make up my own ending instead. That's probably where my interest in fanfiction came from, though I didn't know there was an actual term for it at the time. A few of my favorites are Star Wars, Hatari!, The Great Escape, The Searchers, Pirates of the Caribbean, and Dragonheart; Sherlock, The Fall Guy, Doctor Who, Endeavour, Young Justice, Bonanza, and Star Trek: The Original Series; the Hunger Games trilogy by Suzanne Collins, Spencer Quinn's Chet and Bernie mystery series, the Chronicles of Narnia by C.S. Lewis, Arthur Conan Doyle's Sherlock Holmes mysteries, and The Hobbit, Lord of the Rings, and Silmarillion by J.R.R. Tolkien. I enjoy the Lord of the Rings movies as well as the books, but have to admit that I'm not such a fan of the Hobbit trilogy. They were just... really bad. The CGI elements were clearly CGI, the characterization was terrible, most of the plot was completely made up by the writers (As an adaptation there were bound to be differences between the two, but sandworms?), and the amount of continuity errors is incredible. The wind lance, for example, which was created solely by the writers, explicitly mentioned by Balin as the only way to slay a dragon, and even warranted a flashback in Desolation of Smaug to emphasize it's future importance. And yet no one even suggested that Bard use it in Battle of Five Armies. It's as though it never existed, despite the aforementioned buildup in DoS. Seriously, they didn't even include a two second shot of the lance surrounded by fire to explain why it wasn't/couldn't be used, so as far as the audience knew it was just fine! Instead they had Bard create a giant longbow using his own broken bow, utilizing his son Bain's neck as an arrow rest (and no, Bain does not volunteer for this), which is not only ridiculous but pretty damaging to Bard's character as well; he's supposed to be a loving father here, and he's using his 12 to 14-year-old son's neck as an arrow rest!
Also, you would think that a film titled The Hobbit: Battle of Five Armies could spare twenty minutes of screen time for either is titular battle or titular hobbit, who barely seemed to manage that much screen time even when you add their scenes together. Seriously, the movie should have been called Thorin's Quest: Battle of Ravenhill, because that's what got the most time and attention.
Well... Now that we've got that out of the way (sorry about the impromptu rant), let's move on to something less inflammatory, like pairings.
I tend to go with canon pairings most of the time, though there are a couple exceptions, such as in the case of Young Justice, where I have to admit that I have never been a fan of Chalant. I just find it kind of creepy, since there was a bit of a Batman/Zatanna romance in the comics for a while (or hints of one, anyway) and she was kind of a childhood friend of his too, so they've basically de-aged her just to ship her with Robin. Not to mention there's no real point in them having done this, because romance aside her spot as Team magician could have easily been filled by her canonical younger cousin, Zachary Zatara, which means her only real purpose was to provide a love interest for Robin, and even that was pointless because he still winds up with Barbara/Batgirl in season two. I do, however, really like the other canon pairings: Spitfire, SuperMartian, etc.
I'm not really a fan of romances between Sherlock Holmes and Irene Adler either, regardless of what adaptation they're set in. I think that they respected one another a great deal due to their mutual intelligence, but that doesn't mean that they 'loved' one another. And while modern adaptations seem determined to ignore it in order to portray her as a kind of 'femme fatale', the fact is that Irene Adler becomes happily married during A Scandal in Bohemia, and never once questions her feelings toward her husband even after meeting and observing Holmes; in fact, she shows absolutely no romantic inclination toward him whatsoever during the course of the story, and neither does he toward her. I mean, the fourth line in the entire story reads, "It was not that he felt any emotion akin to love for Irene Adler." And that, to me, pretty much says it all.
To be honest, I think that the modern interpretation of them being 'a perfect couple' comes from the claim that Irene is the only woman ever to fool Holmes, which isn't exactly true, since Effie Munro managed to do so in The Adventure of the Yellow Face. True, Effie wasn't aiming to fool him (she wasn't even aware that Holmes was on the case), but that doesn't negate the fact that she did; it just means that she's the only person in ACD canon who can claim that she fooled Holmes (literally) without even trying. ;)
The only other notable exception would be (surprise, surprise) the canon pairings in the Hobbit films. Specifically the only canon pairing of Tauriel and Kili, though I don't much like her paired with Legolas, either. A lot of it has to do with the fact that I don't like Tauriel in general (she's just not a likable character, which is a shame, because she could have been a great edition to the main cast if she'd been better done), but there's actually a lot more to it than that. For example, she only ever interacts with three other characters (Thranduil, Legolas, and Kili), and out of those three characters two have major personality shifts when she's around. Kili, for example, goes from a joking and rather reckless young dwarf who shares a very close relationship with his brother to a guy who makes sexually suggestive comments to a woman before even learning her name and never once appears to even think about Fili once Tauriel appears in his life. Legolas is the only one not to have any such personality glitch, but that's mostly because he has all the personality of a postage stamp to begin with in these films, and apart from two and a half scenes with his father Tauriel is the only character he ever interacts with anyway.
...But apart from those exceptions I pretty much stick with canon.
If you've actually made it this far after those Hobbit-related outbursts, congratulations; you deserve a reward. Here are a few of my favorite quotes, if it makes you feel any better. And what better way to start than with one from (You guessed it!) The Hobbit.
"If you must know, his name is Beorn. He is very strong, and he is a skin-changer."
"What! a furrier, a man that calls rabbits conies, when he doesn't change their skins into squirrels?"
"Good gracious heavens, no, no, no, NO!"
-Gandalf the Grey and Bilbo Baggins, The Hobbit
"I wish it need not have happened in my time."
"So do I, and so do all who live to see such times. But that is not for them to decide. All we have to decide is what to do with the time that is given us."
-Frodo Baggins and Gandalf the Grey, The Lord of the Rings: The Fellowship of the Ring
"Some people live more in twenty years than others do in eighty. It's not the time that matters, it's the person."
-The Doctor, Doctor Who: "The Lazarus Experiment"
"Knowing someone isn't coming back doesn't mean you ever stop waiting."
"The point is that too often man becomes clever instead of becoming wise. He becomes inventive but not thoughtful. And sometimes, he can create himself right out of existence."
-Rod Serling, The Twilight Zone: "The Brain Center at Whipples"
"You know Laurie, I was just thinkin' that maybe it's about time you and me started goin' steady, huh?"
"Why Martin Pawley, you and me been goin' steady since we was three years old!"
"'Bout time you found out about it."
-Martin Pawley and Laurie Jorgenson, The Searchers
"It does not do to leave a live dragon out of your calculations, if you live near him."
"I know why you brought me the dragonslayers. You wanted them to kill him because you wanted me dead."
"I wanted to correct a mistake made years ago, when I saved a creature not worth saving."
"How unmotherly of you."
-King Einon and Queen-Mother Aislinn, Dragonheart
"How shall a man judge what to do in such times?"
"As he has ever judged. Good and ill have not changed since yesteryear; nor or are they one thing among Elves and Dwarves and another among Men. It is a man's part to discern them, as much in the Golden Wood as in his own house."
-Éomer and Aragorn, The Lord of the Rings: The Two Towers
"But again, if you ask people to describe how they've behaved over the years, you will often find that they say they've looked at it very differently, according to the stage of life that they're at. Here I am, for example, sitting here with all the wisdom of my sixty years--what a thought, sixty!--and I can definitely see how I've looked at things differently after forty. I'm less tolerant of bad behavior, I think, than I used to be. And why do you think that is?"
"You get a bit more set in your ways? You become more judgmental?"
"And what is wrong with being judgmental? It drives me mad to hear people say: 'Don't be judgmental.' That's moral philosophy at the level of an Australian soap opera. If people weren't judgmental, how could we possibly have a moral viewpoint in society? We wouldn't have the first clue where we were. All rational discourse about what we should do would grind to a halt. No, whatever you do, don't fall for that weak-minded nonsense about not being judgmental. Don't be excessively judgmental, if you like, but always--always--be prepared to make a judgment. Otherwise you'll go through life not really knowing what you mean."
-Domenica Macdonald and Pat Macgregor, Espresso Tales (A 44 Scotland Street Novel)
"Has it occurred to you that there's a certain... inefficiency... in constantly questioning me on things you've already made up your mind about?"
"It gives me emotional security."
-Spock and Kirk, Star Trek: The Original Series, "The Corbomite Maneuver"
"Emotions can't be trusted. They can make us do things that we maybe shouldn't do. You have to be careful."
"But don't emotions help us to do the right things sometimes?"
"I don't think so. Well, maybe sometimes. But not usually. We sort of tell ourselves what we want to hear and the more we do that, the more we begin to agree with ourselves--and maybe get fooled into thinking what is wrong is actually right."
-Beth and Mary Fassler, The Dog That Talked to God
"You didn't beat me; you ignored the rules of engagement! In a fair fight I'd kill you."
"Well, that's not much incentive for me to fight fair then, is it?"
-Will Turner and Jack Sparrow, Pirates of the Caribbean: Curse of the Black Pearl
"Much of the modern resistance to chastity comes from men's belief that they 'own' their bodies--those vast and perilous estates, pulsating with the energy that made the worlds, in which they find themselves without their consent and are ejected at the pleasure of Another! It is as if a royal child whom his father has placed, for love's sake, in titular command of some great province, under the real rule of wise counsellors, should come to fancy he really owns the cities, the forests, and the corn, in the same way as he owns the bricks on the nursery floor."
-Screwtape, The Screwtape Letters
"Flailing and thrashing, Buttercup wept and tossed and paced and wept some more, and there have been three great cases of jealousy since David of Galilee was first afflicted with the emotion when he could no longer stand the fact that his neighbor Saul's cactus outshone his own. (Originally, jealousy pertained solely to plants, other people's cactus or ginkgoes, or later, when there was grass, grass, which is why, even to this day, we say that someone is green with jealousy.) Buttercup's jealousy rated a close fourth on the all-time list."
-The Princess Bride
"All get what they want; they do not always like it."
-Aslan, The Chronicles of Narnia: The Magician's Nephew
"Then what's your plan?"
"My plan is to make sure everything is just perfect for your wedding. I called and rescheduled the photo shoot without giving too many details."
"You don't even have a phone."
"Effie had that fixed. You know she asked if I wanted to give you away? I told her the sooner the better."
-Katniss Everdeen and Haymitch Abernathy, Catching Fire
"It is curious how often you humans manage to obtain that which you do not want."
-Spock, Star Trek: The Original Series, "Errand of Mercy"
"Hello, little brother. How's the exile going?"
"I've only been gone four minutes."
-Mycroft and Sherlock Holmes, Sherlock: "His Last Vow"
"You know, kids, I've been thinking about my next picture. I'd like to try something light next time. Maybe something romantic. Why don't they ever make pictures like that anymore? You know; two brothers. One's a Yankee and the other's a South Korean. They don't look anything alike and I play both parts."
-Hawkeye Pierce, M*A*S*H: "Yankee Doodle Doctor"
"I had no idea that shoes could cost nearly as much as a car."
-Samantha Moore, Dear Mr. Knightley
"A Jedi Knight? I'm out of it for a little while and everybody gets delusions of grandeur."
-Han Solo, Star Wars: Return of the Jedi
"One may tolerate a world of demons for the sake of an angel."
-Reinette, Doctor Who: "The Girl in the Fireplace"
"Why did you do all this for me? I don't deserve it. I've never done anything for you."
"You have been my friend. That in itself is a tremendous thing. I wove my webs for you because I liked you. After all, what's a life anyway? We're born, we live a little, we die. A spider's life can't help being something of a mess, with all this trapping and eating flies. By helping you, perhaps I was trying to lift up my life a trifle. Heaven knows anyone's life could stand a little of that."
-Wilbur and Charlotte, Charlotte's Web
"We're going to win this war, you know, now that our army's together. But the world doesn't care who wins. It'll go on spinning, no matter how many people are slaughtered. No matter if you or I are slaughtered. I almost wish it wouldn't, if we aren't allowed to go on spinning with it."
-King Nash, Fire
"What I need is the dandelion in the spring. The bright yellow that means rebirth instead of destruction. The promise that life can go on, no matter how bad our losses. That it can be good again."
-Katniss Everdeen, Mockingjay
"I can't see! Are the stars shining tonight?"
"Brightly, my lord! Brightly."
"Then let us end it."
-Draco and Queen Aislinn, Dragonheart
"I tried to save the Shire, and it has been saved, but not for me. It must often be so, Sam, when things are in danger: someone has to give them up, lose them, so that others may keep them."
-Frodo Baggins, The Lord of the Rings: Return of the King
"There is more in you of good than you know, child of the kindly West. Some courage and wisdom, blended in measure. If more of us valued food and cheer and song above hoarded gold, it would be a merrier world. But sad or merry, I must leave it now. Farewell!"
-Thorin Oakenshield, The Hobbit
