I don't think a review of this movie has been posted, but I saw it mentioned (by Screenor) in one place. Sorry if it already has been.
This is an excellent movie. It's pretty morbid in places, but it's necessary for the effect they're going for. Chromium Bass watched it recently and it sounds like he agreed with me. It's one of the better movies that I've watched in a while.
The plot follows two detectives as they try to find a killer who's committing murders against those who are guilty of one of the "seven deadly sins."
