How bad is it? Trying to be edgy, it's a dull would-be thriller.
Should you see it? No.
I've heard that this film made about $300 during its opening weekend (not $300M, but $300.00 total). The cast is probably more familiar to British audiences than to me, as are the locations and the accents. Supposedly, a film crew with hidden cameras follows a pimp for a week. This falls apart when characters - and there are a LOT of them - talk to the supposedly hidden cameras and when the cameras follow where they could not possibly go. The film goes from a pseudo-documentary, however, into thriller territory, as the main character comes to believe a faked snuff film might be real and he goes to save a woman; the characters, poorly established, do things that they wouldn't do. There's a twist ending that's not surprising or compelling. There's violence, nudity, depravity and so on, but it's minor-league at best. I know sleazy and this ain't it.
