There's a lot of long boring stretches in this one by cult-movie favorite William Girdler but I still find it a pretty good 70's gore flick. It's kind of like a crappier version of THE TEXAS CHAIN SAW MASSACRE( both were based on Ed Gein's antics). You do get decapitation, death by pick-axe, shotgun mayhem and exactly what the title promises which is often a rare thing with these kinda movies. There's also a long interlude where some 70's rock band jams. Of course it's tough to live up to the awesome title but you could do worse if you're looking for some cheap bloody thrills.
This might be one of my favorite trailers ever! What great narration!:
