This is really quite a good film...
At first I was expecting the usual, crappy storyline and badly made slasher film, but it turned out to be a good whodunnit, and despite figuring out who was the killer after a short while, it was really enjoyable.
Some great gory bits and quality story. I loved the little surprises, refrences and nods to other parts of the film like the Humpty Dumpty song and whole idea behind the story, and the "crotch-grab" at the end!
I'm glad I found this classic! :D
