The concept of this movie--girlfriend turns into serial killer on a road-trip--has potential, but it isn't really fulfilled. The production quality is good, and the acting is OK, but the story just isn't well told. There's not enough character depth, not enough tension, and ultimately not enough horror. And at points the plausibility of the characters' actions is so strained that it seems like there must be scenes missing. No doubt there were limitations due to the budget, but what's the point of making a film when the product is less compelling than a TV episode? Not entirely a waste of time since the actresses are at least enjoyable to watch, but disappointing.
