This is not Ed Gein. Not the basis for Psycho or Silence of the Lambs psychopaths, this is Hollywood at it's worse.
How about "extremely loosely based on real events"? It's free but don't waste your time, there is more real horror in watching "the real wives" of whatever it may be. Now that is real and scary...very scary .
This is a pre pubescent attempt of capturing the madness that was Gein.
