Ratatouille is GREAT! I loved how they did Remy's sensitivity to taste. Blue Planet is good, too.

Another is Gone with the Wind. I saw it for the first time when I was 8 and was enraptured.

I rewatched Wizard of Oz with Mr W a few weeks ago and he was spellbound and fell asleep on my lap watching it.

Anastasia (1997) is another well done animated film.

"The Abyss - Special Edition" is a great movie. Might not be appropriate for for kids under 12 (ie the drown & resurrection scene), but it is a good depiction of small group dynamics in a very technological setting while encountering Aliens, with a lot of little things in every scene that GT kids will pick up on.
