I just watched one of the darkest and most disturbing old cartoons I've ever seen. It followed a little homeless girl in NYC on New Year's Eve, and starts with her being ignored and knocked around by all the adults. She finds a place to sit out of the way and keep lighting matches and they keep getting blown out, until she appears to die and go to heaven, but her heaven gets blown away by a bilzzard and it turns out she was just asleep and didn't die. But then she does die and an angel comes a takes her away heaven for real.
That was not the lighthearted, silly cartoon I was expecting.
