I like both the 1951 and 2010 versions very much. I just watched the 2010 version again the other day. I think Depp nailed the role of Mad Hatter! (Even if he let a little Captain Jack Sparrow in there on occasion.)
I've actually seen almost all of the versions listed, I just like the 1951 Disney the movie the best. However, I think it's unfair to compare traditional animation with live-action/CG so I also gave a vote to the "Johnny Depp" Alice .
Funny, when I was little I loved the Fiona Fullerton one, but as an adult I can't stand it.
Every time I see even mentions of the Tim Burton one I want to punch something really hard in the face. I don't know how he went so downhill he used to be a great original director. Now he ruins things from my childhood.
I've only ever seen the Disney film, the 1999 film, and Tim Burton's version... I haven't seen the 1999 version in so long, but I remember really enjoying it. Don't think I can cast a vote unless I watch it again, just to be sure.
Dangit, this makes me want to read the books again!
