What FanFiction.net really needs:
1. Slash/mpreg filter - I don't want to read this crap, especially when half the authors lack the basic courtesy to include warning in the summary.
2. The ability to block/hide individual authors/stories from search results. Twisting the Hellmouth allows people to at least hide stories and it is so nice - once you hide a story, you personally never have to see it again. FF.net has so much Harry/Draco or Harry/Snape crap that fan girls seem to love and so it constantly shows up on search results. I would love to block it once and never have to deal with it again.
Things that make me go "WTF" about JKR's Potterverse:
Dumbledore - I despise Dumbledore. This hasn't always been the case - when I first read through the HP books, I viewed Dumbledore through the lens of Gandalf and didn't examine his actions closely. With closer analysis, I've come to the conclusion that Dumbledore is either evil, insane, or some combination of the two.
Dumbledore is one of, if not the most, powerful wizards around, especially after the defeat of Lord V. He is the head of the ICW and the wizagoff. He is the headmaster of the premier magical teaching institutes in England and has the capability of influencing an entire generation of students. And what does he do with all of this power to oppose the return of Lord V or the rise of another dark lord? He forces a baby onto an abusive, magic-hating couple. THATS ALL! What does he do about all of the deatheaters who bribed their way out of prison time? - Nothing. What does he do about the werewolf laws/attitudes that basically force them to support Lord V? - Nothing. What does he do about the Pureblood attitudes that enabled the rise of Lord V? - Nothing.
What is he doing during the 11 years between the disembodiment of Lord V and Harry's arrival at Hogwarts since he seems too busy to check on Harry and ensure that he is being taken care of? Unless letting Harry be abused fits his plans. Which it seems that it must since he constantly forces him to return to the Dudleys and does nothing to stop their abusiveness. In fact, he admits late in the series that he knew he was putting Harry into an abusive situation.
A perfect example of the "wisdom" of Dumbledore - Peter Pettigrew escaping at the end of Book 3. Dumbledore supports Harry showing mercy to Pettigrew and allowing him to escape. And what happens - Pettigrew is integral to the return of Lord V and the death of thousands, if not 10s of thousands, of people. Brilliant. And what good did this supposed life-debt between Harry and Peter do?
Or his attitude towards Snape - I don't care how useful Snape was as a spy against Lord V, that does not justify allowing him to ruin an entire generation of potion students and stop numerous potential aurors and healers from entering the field. How much did he weaken the country just because he wanted to keep his pet deatheater close by?
Or the bloodwards around the Dursley's house - If the bloodwards were so effective against deatheaters, why did the Order of the Phoenix need to have so many people guarding it? And how did he expect the wards to continue to be effective after Harry's blood was used in Lord V's resurrection? And if it was so necessary that Harry return to the Dudley's for his safety, why was he removed after a few weeks to go to the OotP's headquarters?
"Harry Potter & The Fall of a Dark Lord" by Kalen Darkmoon is a wonderful summary of everything wrong with how Harry was treated by Dumbledore. Her profile is also very insightful.
I can not find any logical, moral explanation for Dumbledore's actions, particularly towards Harry. I believe that Dumbledore deliberately created the conditions that led Tom to become Lord V and that all of his actions towards Harry are to try to mold him into a disposable weapon to use against Lord V.
What do I think Dumbledore should have done? First, in the weeks following the disembodiment of Lord V, all of the Deatheaters who escaped Azkaban (and their families) and all of the Wizengamot members who accepted bribed to let them go - they would all vanish. Permanently. Ensure that even if Lord V returns, his power base of supporters is destroyed. Every member of the Ministry and all aurors would be questioned under Veritaserum to ensure that they were not supporters of Lord V. And very shortly after Fudge totally rejected the possibility of Lord V returning (if not far sooner), he would have had a heart attack or fallen down the stairs and broken his neck or something. He was far too small-minded, bigoted, and power-hungry to be allowed to live.
If one choses to let a Deatheater live, he/she is now personally responsible for every death that person causes, since they could have stopped it from ever happening.
Order of the Phoenix - What good were they? They were utterly passive. They only reacted to enemy attacks - no counter attacks were ever considered. The identity of many of the deatheaters were commonly known - ie Malfoy - but they were allowed to move freely and without hindrance. Why wasn't the Order running assassination missions or fiendfiring the houses of the supporters? Why weren't they destroying the resources that allowed Lord V to be funded? Why didn't the houses of the supporters have lethal wards around them? Why weren't they training to fight as soon as any sign of Lord V showed up?
McGonagall - Now I generally like Professor McGonagall, but some of her actions are inexplicable to me. Why did she take 50 points each from Harry and Co when they were caught out after curfew - that's extremely excessive for a group of first years on their first offense. Why not just a warning or a week of detentions? She is supposed to have enjoyed the antics of the Marauders - so why does she seem to be trying to destroy a similar exploratory/bend-the-rules attitude in Harry? Or why did she ignore their concerns about the stone - even if she has utter confidence in the protections, why wouldn't she double-check? Heck, I'll double-check to make sure I didn't leave a light on before I leave the house, let alone when protecting a priceless, one-of-a-kind magical artifact. How long would it take anyway? And considering how lame the protections were, she shouldn't have had that much confidence in their ability to keep out anything. And where was she while her students were being tortured by Umbridge with a highly-illegal blood quill? Either the students didn't trust her to protect them (huge issue if that is the case) or she was too cowardly to protect them. There was any number of things that could have been done to stop the torture - legally or illegally. Personally, I would have picked up a spare wand at a second-hand store, imperiused Umbridge to write lines with the blood quill until she bled out, cleared the magical signature remaining in the area, and then destroyed the wand. But if one wanted a more legal/less bloody solution, sending pictures of what was going to to the Quibbler, school board members, and all of the parents would have lit a political firestorm that would have destroyed Fudge's administration. And was McGonagall the genius who thought it would be a bright idea to send first year students into the Forbidden Forest, at night, with something capable of killing unicorns running around?
Pairings I like:
Harry/Hermione - best friends to lovers, the smartest witch of her generation ending up with the Boy-Who-Lived, seems the most natural to me.
Harry/Fleur - Hot intelligent talented blonde. What more needs to be said, except that I would be jealous.
Harry/Gabrielle - generally doesn't work within the timeline of the books due to the age difference (not a fan of pedaphilia), but a relationship forming Harry saving her life seems more natural than Ginny's wanting to marry the Boy-Who-Lived, especially if one throws in some type of life-debt/bonding.
Pairings I hate:
Harry/Ginny - I don't like Ginny. I'm not exactly sure why, though the stories where she uses a love potion to get Harry seem very believable to me. I guess the fan girl -> stalker seems more logical than fan girl -> girl friend
Harry/Draco or Harry/Snape - I'm generally uninterested in slash in general, but I truly can't understand the fascination with these two pairings. Harry with the arrogant kid who he has been fighting with ever since they met or Harry with the bitter, nasty, Deatheater potion master who has attacked/belittled/etc constantly from the first class? What are these people smoking...
Ron/Hermione - What the hell was JKR thinking anyway when she put these two together - the smartest witch of her generation with the lazy slob who constantly argues and insults her? Though Jeconais in his story Hope does do a wonderful job of showing a mature, loving relationship between the two.
