If you are looking for a regular movie, a movie with a regular hero, don't waste your time on this movie. It is anything but "normal". It's tone is going up and down and spinning all around. You have a main character that you probably learn to hate over the course of time. Which is quite a hard thing to demand from the viewers. Especially considering we are laughing at first with him. We are maybe even connecting with him. From his birth (literally) we follow him ... who would have thought the path he'd take? And the atrocities he'd commit - but that is just what you get served here.
And topping everything off, something I wasn't aware of, this is based on a true story and real people. The depravities in this, be it sexual or violence wise ... not easy to cope or digest. Some of the sex scenes go beyond .. really almost all the way (without showing something explicitly), but feeling as if they are real. Not for the squeamish for sure and really takes a toll on the viewer. If they decide to take the ride with a man who seems beyond redemption ... or is he?
