How bad is it? It's a dull police procedural.
Should you see it? A few unintentional laughs can be had, but not enough.
I think this film gets slammed in reviews because it looks like a slasher film, but isn't. The zipper-masked villain is not seen for much of the film and the story follows a young female detective trying to solve the case. The acting is atrocious and the plot has several holes and improbabilities. The actual identity of the killer will surprise you however (it may also leave you shaking your head), so it has some merit!
