I will give credit where credit is due, the set design and makeup is decent, but that's is it for the positives for this film. This movie wouldn't be enjoyed by anyone with a mental mentality over a 12 year old's. The characters are as cookie cut as they come, the snobby rich kid, the over sexed teens, and you just want them to hurry up and die faster so you don't have to cringe at their presence any longer, I don't think you were meant to side with the murderers in this movie, but that's what it makes you do. at one point I was saying to myself "they better make that douche suffer" Our hero in this movie, the ex Seal is incredibly unbelievable, due to equally bad acting and fighting choreography. Having making a thing about being "aware of your surroundings" you could sneak up on this idiot on bubble-wrap carpet while tap dancing in golf shoes.
The thing I found most infuriating about this movie is the Seal was trying to save his girlfriend and the cookie cut kids but wasted all these precious moments in the woods building elaborate booby traps, with the hopes that a single antagonist would stumble through, among the dozens, while he was playing Rambo in the woods, his main objective was being raped and murdered, it wasn't until the climax that he decided he had enough of playing Hunger Games in the woods and decided to go save his girlfriend.
The whole movie was just a sloppy, badly thought out mess, and a complete waste of time, so hopefully you will decide to not endure this film like I have.
2/10 set design and makeup is the only thing that justified not giving it a 1/10.
