Same old prolonged intro of helicopter camera view of car driving along country road. Same old "no cell phone reception" used in a hundred similar movies and to which there is actually a website devoted to that unlikely cheap hook. Same old formula (and really poorly - acted, written and every other possible cinematic category imaginable) story of of slightly mentally not-quite-there family that captures a couple of travelers for a bit of torturous fun. You see nothing except a little post event red food color corn syrup as fake blood.
Specifically, young woman (as usual) parks a block from a semi-remote river to deposit dad's ashes. A not believable encounter with a guy walking by and a not believable scene where she walks back up the river bank to the parking area to find her car is not there. The usual sequence of "you've got to be kidding me" poor decisions that only appear in really bad movies now occupy the rest of the movie. These movies almost always end in one of two ways so ff and avoid yawning.
