The success of The Simpsons really opened doors. It showed that if you were working in animation you didn't necessarily have to be working in kids' television. ↗
And having suffered for part of the war when I was a child. I was too young to really understand what was going on but one of my favorite pieces of animation now is that Goodbye Blue Sky in The Wall because that deals directly with that period in time. ↗
I just find it interesting that kids apparently used to cry when Bambi's mother died. George and I both held our breaths, and then cheered when she didn't reanimate and try to eat her son. ↗
