Animated 3D movies that might just be too childish for adults

[levcore]

Tricky to word the title of this post, but basically, i've been picking up a lot of animated 3D movies since getting my setup. Please bear in mind i watched virtually no animation before getting a 3D TV. Now i watch quite a bit. I just wanted to gauge people's opinions on which movies they think might perhaps just be too childish for adults to enjoy, so i can avoid picking up any kids movies, that really are solely for kids. I bring this up because i got Animals United, and whilst the animation is nice enough and the 3D is great, the movie is really aimed at a very young audience and is something that i don't think a grown up (even one who's young at heart!) can enjoy. Are there any others like this? For example, how about Rio and Megamind? These are two that i have a chance of picking up and don't want to, if they really are just for kids.

To counter this, one that might crop up is A Turtles Tale, however i let that one slide as the 3D is the best (as we all know).
