Very strange. The flicking backwards and forwards to movies that were inspired by Gein is off putting. The storyline is also obviously embellished, but if you haven't read, or seen anything about the real story, then that won't bother you. Charlie Hunnam plays a good part, except for his portrayal of Geins voice, which comes across as an Irish kermit the frog in some scenes. I was glad when I got to the end of it, but that said, I suppose it could have been worse. Its kind of entertaining in a weird way. I've given it 3 out of 5, but I really rate it as 2 and a half.
Its not something I'd rush to watch again.
