I give this movie my certified stamp of "I liked it".
I think the sub genre of camping-horror is pretty underutilized outside of Blair Witch derivatives, or the "oh no we're being hunted by a Sasquatch" slop that keeps getting made, so this movie doing something a little more unique was refreshing to see. The monster has a great design, and the surreal aspects of the convenience store incident popping up throughout was well done.
