My uncle used to have this copied on a tape with Fear No Evil and I often used to treat myself to a scary double bill back when I was a young 'un (around 12 years old I think I first saw this). I recently managed to pick it up on DVD on the Mill Creek 50 Chilling Classics collection, and while the transfer leaves a lot to be desired it does appear to be uncut and is certainly longer than the versions i'd previously watched. I think there's a very good chance that i'm the only person on this planet that thinks of this film as a minor masterpiece. There are some genuinely frightening scenes in the film (the bizarre multi-coloured hand that kills the teens, that evil laughter, the group of demons that kill Emily, the intrusion of the old woman in her bed) and the gore is certainly no worse than countless slasher films from the same era. The obscurity of this film means that very few people will ever get to see it and judge it fairly. It obviously cannot be compared to classics such as The Exorcist, TCM, Suspiria and The Evil Dead but as far as obscure minor horror pieces go, you could do a lot worse. The idea in itself is a fairly original one, of a bunch of warlocks coming back to life to destroy a town and reclaim Ludlow's severed hands while taking refuge in a giant white piano and coming out every now and again to murder the grandchildren of the people who killed them! I don't think some people (or all the reviewers here) actually comprehend how low budget this film was and when you consider how ambitious it is, you can't help but respect the makers of the film. Acting-wise there is nobody particular of note with barely any of the cast members starring in anything else! They do their jobs admirably and while there's no Oscar winner material from anyone, no-one falters. Just give the film a chance and maybe you'll enjoy the film as much as I do. In fact...i'm gonna watch it again right now!...
