Extremely Claustrophobic and Bloody Demon Doings. It is one of those that the Evil Entity can leap from Body to Body. The Atmosphere is sometimes Chilling and the Gore is Prevalent while Weak Characters are put in Jeopardy in a Regular Rhythm of Gross and Disgusting Displays of Horror Movie Tropes.
But there is enough Splatter in this B-Movie to give it a Pass on the Familiar way it goes about its Story. None of the People here are Relate-able and some of Their Back Stories are so Glossed Over the Victims remain Nothing but Props.
Some Creepiness is at hand and the Movie does make for a bit of Unsettling Reaffirmation that when told that a Road is Unusable, the Horror Movie Thing to do is, well You Know. This Leads to the Clichéd Set-Up of the "Cabin in the Woods" Variety of Pent Up Spirits and many Brutal Deaths ahead.
Overall, there is Something here that makes all of its Familiarity somewhat Watchable for Horror Movie Fans. Just don't Expect Anything other than a bunch of Semi-Clever Kills with an Eat Your Own Tail Ending.
