I was convinced Kung Fu Panda 2 would be absolutely awful, after I wasn't all that impressed with the original. Unlike most kids movie sequels though, they seemed to go the more serious route rather than a completely harmless villain.
Despicable Me was definitely another movie that was a lot better than I expected. I think I just have low initial expectations of children's movies after almost all the ones I watched growing up were terrible.
I don't even know what to think of Warm Bodies. I guess it depends on if they go full out spending every second of airtime parodying Twilight, or if they actually try to carve interesting characters and a story out of it.
