Author has written 3 stories for Doctor Who, and Torchwood.
I read mostly Star Trek TOS, ST Reboot and Doctor Who. With some Torchwood, Red Dwarf and Firefly. That said, I've read A LOT of them. (DW crosses with RD so well btw)
I particularly love the crossing of timelines, good dialogue and Nine in general.
I tend to dislike stories not keeping to canon, although some bending can be ok. The one thing I can't stand is people writing characters totally OOC, like many Rose/10 shippers tend to do. I must admit to shipping myself, but come on - keep it believable at least. Even if it is PWP. Oh, and I abhor bad spelling/grammar.
A couple of thoughts:
Why isn't there any stories where the Doctor runs into John Hart?
Oh, and there really should be a "10th Doctor metacrisis / TenTwo / 10.5 / Handy" character option on FF.
Nothing beats K/S though.
