There's a Russian film called Night Watch about vampires (it's actually called something in Russian). If you get the decent DVD/Blu-Ray version, the subtitles are all animated. So they'll get swiped off the screen, or bleed away, shit like that. It's a small touch, but awesome.
I also like it when animated food makes you want to eat it, even though it barely resembles food. Ghibli films are excellent at this. I think it's the sound, and the way the characters tear it apart.
