Up was good but like, I felt it was completely off tangent, like it didn't know what it wanted to be: classy cartoon film for adults or cutesy harmless comedy for children? The parts in the jungle didn't really resonate with me and I felt the sidekicks made it feel like a generic movie. It has a lot of great ideas, such as the story of the old man coming to terms with his childhood dream, but the bulk of the film felt uninspired -- from the villain, to the sidekicks, to the plot. Up is entirely front loaded and back ended to be enjoyable on subsequent viewings. Really good movie, just not one of Pixar's greatest and I *love* Pixar. I almost put Up on par with A Bug's Life.
I enjoyed Kung Fu Panda far more.
Megamind looks fun too and I honestly don't understand how anyone can describe Megamind as a typical Dreamworks picture. The premise alone is unique for an animated feature film for kids in a time when talking animals or talking _____ is de facto standard. Everyone has wondered at one point in time "what would happen if the villian actually WON?" and Megamind panders to that line of thinking; the premise is pretty inventive, not even just as a Dreamworks movie, but as an animated film as well. That said, that's all from media and trailers, the movie itself could prove me wrong, though.
