It was good. The animation was stunning. I cried (altho that's not unusual), but, the best? not sure about that. It's a good story, but pretty mono-dimensional. I know that's kind of what you expect in a kids movie, but Pixar had already raised the bar on that so high I kind of expected more.
Madagascar was good but also not great for the same reason I thought. (vv .. and I know it's not a Pixar movie, and i enjoyed it also, but it wasn't "great", because it's plot, although lovely, wasn't as nuanced, layered or stirring as a great film's should be, like many Pixar films have been, but not to my mind Cars. Cool, good, enjoyable, funny, in parts stunning, not truly great)
The Incredibles is still their best yet for me.
