Brilliant film. Pretty tweaked out and unusual spin on the Slasher movie. It has elements of TCM, Carrie, Deranged (the best Ed Gein based film IMO) and Psycho blended together to make a really offbeat creepy movie. Chuck Conners was great in this role and pulled off the deranged madman really well i thought (the part with the killer plastering over a womans face and describing to her what's happening to her body as she dies was really fucked up). Another fine example of 1970s U.S horror cinema, pity they don't make 'em like this anymore.
.......mannequins will always creep me out after watching this one :(
