First off, what is teased by the trailer and what is actually delivered is best described as a "bait and switch". This movie is not a sci-fi or a dystopian future adventure but a "Friday the 13th" themed horror with a sprinkle of Deliverance.
It's not bad, it's not good and uses the same formula as a hundred other formula type teen horror movies. I will easily forget this one. Over all a C+.
