Just watched this, and although I enjoyed it and found it was good, something really bothers me about movies like these.
The entire portrayal of a 'freak' who is displayed as a charismatic, good looking guy turned invincible slaughterer couldn't be far from the truth. A real freak, or a mentally ill person is someone you would probably never relate with or feel sympathy for, just because of how royally fucked up and repulsive they might seem to be. Someone who wouldn't die as a martyr, but on a lonely death bed, or a ditch in god knows where. All the pseud, edgy conversation surrounding this movie by people who 'relate' to the protagonist, and would go on the next day making fun of people they deem fit to be so.
I guess the ultimate pill is, you really can never relate to a 'freak', maybe its a paradox.
