This is not a bad movie, per se. What you'll get is a throwback to the 80s slasher flicks and a lot of atmosphere. There's a starkness to the way its filmed that gives it a realistic feel. The acting is surprisingly good and the merciless way the killer takes people down is reminiscent of Texas Chainsaw part 1.
My only issue with this movie is that if the writers gave just an inch more effort, they could have come up with some kind of story as to why this is happening. Give us anything....not just some rando killing folks. If they would have done that, I think this movie would have been a pretty solid sleeper.
