Personally, I'm not a fan of these movies...and I boycott them on principal. IMO, you can't beat the perfection of "Snow White," "Fantasia," "Aladdin," etc. I'm old-fashioned I guess, but the traditionalist in me will not allow me to enjoy films in this style. Besides, most of them aren't that special. "Finding Nemo" didn't do much for me...it was all computery & stuff, but it wasn't exceptional. The "Toy Story" movies are cute I guess, but nothing earth shattering. I just never understood why they felt the need to just give up on the classic style of animation.
At least Disney is going back to traditional looking animation...at least for a time, which is good. As long as they don't truly abandon the traditional looking stuff for the Pixar stuff, then I could find those films more tolerable. I think there's room in the multiplex for both styles.
(I did really enjoy "The Incredibles" though...but I watched it as a superhero fan, and not an animation fan...so it gets an exception because of what the film's about.)
