It is a RAPE REVENGE flick people. Unless you are into actual on screen castration and torture, then don't wast your time. If you are a pervert then just watch it on Heavy R and that way these idiots don't get paid.
I would say it is not a bad movie if you are a Man. It is not really loaded with any Hollywood tropes only the fact that the HER operation system does leave him at the end. But it is explained that the HER operating system is operating on a speed he cannot interface with him any longer.
