Yeah, I've seen far worse, although I agree that it does get a little lost in the middle third of the film (but thats true of most thrillers).
I think it suffered from falling between to genre. Too gory to be a "thriller", but not gory enough to be a "horror".
Plus it didn't help that LinRABay was another of those strippers that doesn't actually take her clothes off, that always makes me laugh as I always think "If i was a customer in that bar I'd be demanding a refund"
