Review of Henry: Portrait of a Serial Killer

although the slow pace of the movie i painfully watched it entirely, as the title claimed to be a 'PORTRAIT" of a serial killer. i expected some psychology, some labor of research, but it was a bland exercise in trying to shock the viewers, i believe you get more information and insights on half a page of a popular daily newspaper, you can tell in advance that serial killers are immoral people with affective problems so what is the idea to show their daily inept lives, without trying to get into their minds ? and it does not qualify even as a horror movie (there is no suspense, no emotions, not even blood) nor a controversial, original movie, "I stand alone" is quite impressive for example, and many documentaries have better treated the subject, don't be intrigued by the title, this is not worth spending time watching
