I agree with "A Bug's Life" being quite forgettable. I vaguely remember it, although I saw it a while back. Not nearly as memorable as, say, "The Incredibles".

My personal favorite is the same as Kroc - Ratatouille. It was a very charming concept, the humor was very clever, and the whole work was simply very well-executed.

I did see WALL-E, and that was a really excellent diversion. It was a very visual experience, as there was no dialog for a large portion of the movie (as already mentioned). It was like watching art - the visuals told so much story in so little time that I'm glad that they didn't try and ruin it with dialogue.

The movie "9" (don't remember for certain if it was Pixar who did that) was a big disappointment to me. It wasn't *quite* as bad as ABL, but I just feel it fell flat compared to others. I really, really wanted to like it, but if the creators wanted 9 to be a "great" movie, they certainly forgot to put that desire into the production of that film.
