Madagascar 3. Okay now obvious is obvious, this movie was a total cash-in, and the original wasn't fantastic to begin with, but I watch all the animated movies out there.
The first half of the movie was mediocre, 'okay' at best, and it was ridiculously fast-paced so that you could hardly tell what was going on. The second half was... better. It wasn't fantastic by any means, but it was much better than the first half. The story ark and exposition of the circus was about as cliché as it gets (losing your touch after failure -> main character gives motivational speech -> redemption), but it was accompanied with some really stunning and creative visuals (the whole movie itself was quite pretty looking), and a few scenes that aught to make people laugh.
I'd definitely give it a pass if you don't care for the genre, but if you want to go see it, it's harmless (aside from a couple shots at Canadians they took throughout the film). If for anything, the last act is very fun. The rest of the movie is mediocre at best, but then again anything is a thousand times better than The Smurfs.
