I love UP! though Ratatouille I'm fairly certain is my favorite Pixar movie to date, with Incredibles coming a close second. Pixar is pretty much amazing.

Ok, mixed fandom: Dukhat, Sirius Black, McCoy.

My current fandoms I'd have to say are B5, Doctor Who (new Who), Star Trek: Voyager, Sector General, Animorphs, Narnia...I think that's all I can think of.
