Time Out review:
Mostly, Ben (Benoit Poelvoorde) is an ordinary sort of guy. One passion, however, is unusual: he regularly commits murder, not exactly at random, but certainly without malice or provocation. So intriguing is Ben's deadly charm that a film crew decide to make a documentary about him; and come to like him so much that they start facilitating, then collaborating in, his crimes. This spoof fly-on-the-wall documentary is funny, scary, provocative, and profoundly disturbing. While the body count is sky high and the violence explicit, it's neither a thriller nor, finally, a psychological study. Rather, it's a witty, uncompromising acknowledgment of both film-makers' and audiences' often unhealthy fascination with the spectacle of violence. Even as you admire its bravura, intelligence and seeming authenticity, such is its rigour that you are also forced to question just why you are watching it. Purely on a gut level, it may offend; but as an exploration of voyeurism, it's one of the most resonant, caustic contributions to the cinema of violence since Peeping Tom.
