There are actually some good ideas buried in here, ideas that, if focused on and properly executed might have resulted in a fairly interesting movie. But as it is, this is a really bad movie. Among other complaints:
(1) The tired and offensive stereotype of the token black member of the group being the first victim
(2) Repulsive protagonists, who come off as utter jerks. Not just jerks, but stupid jerks, making mistakes like wandering off alone, etc.
(3) A cheap and shoddy look. Now I know this was a low budget direct-to-video movie, but that's no excuse - I've seen other low budget direct-to-video movies that managed to look very slick
(4) No scares, no suspense, not even good splatter
(5) Two separate storylines that really don't fit together well.
By the way, despite what's pictured on the front and the back of the video and DVD box, there are NO skeletons to be found anywhere in the movie!
