This isn't bad at all...
I like cartoons. Black humor like that is offen in programms like "Cartoon Network" etc. If someone think that was offensive, think about it and ask a 7-10 year old boy, is this movie offensive. There are more retard movies, and i like this one. Just better graphics. Nothing more to add, mayby little change the main character and this would be good. Always think about that, someone like his own type of humor. I like all.
