I grew up watching every Rankin Bass TV special that was on. I'm guessing that this one wasn't aired much after 1972, because I didn't even know it existed until now. Lots of fun.
Who would have thought the HELLRAISER franchise would make another decent movie after so many lame sequels? It reminds me of how the last HOWLING movie was a breath of fresh air after so many bad movies before it. Though, I do have to say...it seems a lot more like a script modification of SEVEN that they just plugged the cenobites into. Certainly not perfect but very watchable.
