Just the concept of this slow-moving crushing mechanism being used on somebody triggered something in me as a child watching the Teenage Mutant Ninja Turtles movie. At that point, I was content with the turtles' treatment of Shredder in the cartoon series, which was mostly foiling his plans and sending him back to Dimension X, or what have you. Not the movie! Nope, just kill him in the most painful way imaginable and set off a fear of death by compactor that never existed in me until that point.
At least they got Donatello right. Cowabunga.
