"It can be argued, and has been argued by the likes of Brad Bird (The Iron Giant, The Incredibles, and Ratatouille) among others that one shouldn’t discuss animated films as if they are all to be lumped together, since technically the only thing they should have in common is the fact that they are not produced via live-action. I wish that were wholly true. But when it comes to discussing mainstream animated films in America, it is unfortunately a question of genre. Artistically and especially financially speaking, films like Cloudy With A Chance Of Meatballs 2 and Turbo are indeed cut from similar cloth in that they are basically targeting the same audience. We might decry this fact, but American animated films are still considered child’s play, a notion that heavily influences who they are aimed at and how they are made."Unfortunately, when we get something animated aimed at adults, it's because it's unsuitable for children, not because it should be taken seriously by anyone mature. Today's announcement of Sausage Party, an R-rated animated feature by Seth Rogen and Evan Goldberg, does nothing to advance the cause of animation for adults.
We can argue over the terminology, but it doesn't change the facts. North American animation is kid stuff.
