The cover of the DVD will tell you it's a true story, there's no law against bullshit in movies
**edit: On the 'true story' thing, they will say 'inspired by a true story', and that's correct as far as the bloke wears peoples skin. That's where the 'true' part ends. No chainsaws involved, no family of canibals, etc...
There's a few movies out there that cover Ed Gein, they don't make terrible watching.
Other gore movies:
So far today I've suffered through 'Death Tunnel' and 'Feast'.
Death Tunnel is about as much fun as taking a savage beating to the balls with a sock full of nails. If you have a choice between a smack in the teeth and watching this movie, take the smack in the teeth.
Feast is OK, nothing spectacular. Wouldn't go out of my way to see it again, but after 'Death Tunnel', anything looks good.
