All Dogs Go To Heaven and the hell scene? (Actually managed to terrify me a lot more than The Dark Crystal, Labyrinth, Return to Oz or Watership Down. I don't even know.) The 90s didn't give a FUCK.

Does anyone remember Return to Oz? That thing starts out with a preteen in an insane asylum! And just gets worse, pretty much. Needless to say I was riveted as a small child.
