They said that Hangover is pretty hilarious but I prefer Kung Fu Panda 2. So that is one vote for Kung Fu Panda.
I think it is quite difficult to pick one. Both are the fantastic movies. But Hangover 2 is little better than kung fu panda
There is no comparison between these two movies. If you wanna compare and vote for the movies, then compare each of the movies old and new parts, instead of comparing two different movies
