Like, after I saw that movie as a kid, horrible things in other movies didn't really have an impact. Well... That, and I understood movies were all make-belief. I used to love watching making-of features for movies.
I came looking for this. It seemed like this movie came out at that time when adults assumed all animated movies (or cartoons as I was told) are for kids, and so this was shown in our after-school group. There were several kids crying by the end of it, and I may have been one of them.
