I've seen a lot of disturbing animated features, mostly because I seek them out.
I could name something like
Princess, which is a very disturbing animated film that came out in 2006.
Instead, I will leave you with this:
http://www.youtube.com/watch?v=5A9gukuizDUTBH I think stop-motion has more potential to be horrific , princess just looks too clean style to be horrific - but thats me.
Watership Down disturbs me a lot more.
If only there were a whole film based on this sort of stuff
Or the animation tool uses in some of their videos.
