Actually, dislike is probably too strong of a word for my opinion. In all honesty, I just favor Pixar over DreamWorks.
DreamWorks HAS made good 3D films though, I did enjoy the first two Shrek films (the third one was okay, I guess), and Over the Hedge, and I think I will enjoy Kung Fu Panda.
I didn't like Shark Tale, and Madagascar was....eh.
