I found IRREVERSIBLE quite moving, with a strong message about the absurdity of revenge. The woman's former and current boyfriend take revenge on the wrong man, while the perpetrator remains free to victimize others. The revelation, towards the end, that there was an additional, most innocent of victims, was powerful and reminded me that when violence is perpetrated there are often innocent, unintended victims. This Argentinian expatriate(Noe) conveys the horror and repercussions of violence. He refuses to use it for thrills and escapism. I commend your consideration of moral issues few dare to discuss, but you are picking on the wrong film. Violence should be revolting. What may be morally suspect is for a film to make you feel comfortable with the violence on screen, to treat it lightly.
