The 80s were a wild time for kids movies. I loved The Labyrinth but the scene where the puppets took their heads off and played soccer was unsettling. I still don't like that part.
My husband wanted to throw on The Secret of Nimh for our 5yo twins. He was sitting there confused why I would object, "it's rated G." It's 1980s G; that's a Don Bleuth Bluth animation! "It will be fine! Come on kids, this is a movie Mommy and Daddy watched when we were kids." I got up to get a blanket in preparation for the inevitable hiding behind a blanket moments.
