Because, lets be honest, it is not often that an animated film comes out solely aimed at adults. True, over the last few years CGI films have managed to appeal everyone with successes such as Toy Story (1995), Ice Age (2002), WALL-E (2008) and Monsters Inc. (2001). As have some stop-motion films, such as Wallace and Gromit and The Curse of the Were-Rabbit (2005) and Chicken Run (2000).
However, an animated film, aimed solely at an adult audience is a rare thing indeed. After all, when is the last time you saw a Disney film with a 15 certificate? Exactly.
There are only two films, off the top of my head, that I think of can be considered as more for adults. First of all is The Simpsons Movie (2007). Now, technically that is a family movie, but The Simpsons does lean much more to the adult audience in its use of humour and issues. Quite a lot of the stuff in The Simpsons will go over kids heads.
The second, is the indie movie Sita Sings the Blues (2008). A beautiful film, completely animated by one woman, it would probably be best appreciated by adults.
Of course, I don't think these can be the only films. So out of curiosity I decided to do a quick search and see what others I could find. What I found was a top twenty list that reminded me how many excellent animated films there were out there for adults. I couldn't believe I had forgotten them, especially some of my most favourite films, Persepolis (2007) and Yellow Submarine (1968)!
