There was this one movie in my country where a kid shrunk himself and entered his grandfathers body so he could find out what made him sick. So he went on an adventure inside his body and met all these characters.
Some moments from that film scared the ever-loving crap out of me and made it hard to sleep. Don’t know what the film makers were thinking. I watched the movie a second time in class in elementary school and I couldn’t leave the room in fear of embarrassing myself in front of my class mates.
I managed to get traumatized when my mom took me to see Winnie the Pooh and the Blustery Day play as a small kid. Horrible experience. I hate Winnie to this day and I blocked my wife from trying to give the books to our kid when she was small. Can’t think of any movies that did the same, however.
