My brother LOVED Ren & Stimpy, but it was just so repetitive and ugly! I just can't stand to watch it anymore!
It was artistically grotesque. Even the episodes I liked made me feel sort of soiled and unsettled by the end, like gorging on surrealism. I'm not sure I could watch it now.
Two others I'm sure would now make me throw things at the screen, though I loved them at the time, are Lassie's Rescue Rangers and Valley of the Dinosaurs. Anyone remember them?
