Right in the childhood.
Finding Nemo
A man and his wife are admiring their home, when a murder attacks them and brutally kills the wife and all of their children except one. Great premise for a fun movie.
Fox And The Hound
This movie was essentially about how if you are different from someone else, the existential void between you both will inevitably grow so large that your friendship will die. Nice, healthy message.
An American Tail
Another classic topic for a kids' movie: The misery of Russian Jews forced to flee persecution, abuse, and other inhuman horrors in their native land. These ones are mice!
Who Framed Roger Rabbit?
Remember that story about the self-destructive, alcoholic detective who investigates a series of horrific murders by a sadistic maniac? Yeah, that was a great kids' movie.
"Remember me, Eddie? When I killed your brother, I talked... just... like... THIS!"
And if that doesn't do it for you, here's one word that will forever haunt your dreams: "Dip."
