Well the film was a fictional story in which there was no holding back on exagerated depictions of outrageous psychopathic behaviour. Think of all of the films in which police are depicted as violent and evil characters, though there are other films in which the cop is a good person. The point being that all sorts of people and people's sexual and lifestyle choices are used by Hollywood and novelists just to make a story entertaining and gripping. Not much that we croos dressers can do except make sure that our own behaviour is not offensive.
I thought that the film was well made and the acting was very good but I still came away feeling "slimed" and "used" in the sense that all the writer and director did was play to my basest instincts.
