This is a standard teens-against-monsters horror quickie, and you know what that means. There is not one iota of originality in this movie; you've seen every one of these recycled plot devices a hundred times before.
Stock teen character personality types: check. Stupidly going somewhere they shouldn't be: check. In the middle of nowhere: check. Grotesque, vicious ghosts/creatures of some kind that get a kick out of killing teens: check. Teens turning into monsters too, and trying to croak the remaining survivors: check. Weird old man who has a history with the evil: check. Incessant screaming, futile banging on doors to escape, arguing about how to kill the creatures, running around in caves, characters "calming down" each other, lots of red paint on stomachs and necks, surprise attacks from supposed allies on each other, cars that don't run, monsters that just keep on chasing you etc etc etc. Check.
The acting and scripting are even below the established low level for this kind of movie. This one is only good for background noise while you're doing chores; or to laugh at it MST3K style. As for a story? Nope.
