By far the worst horror movie I have seen in years! Primal was terrible. Absolutely, dreadful and I have seen some garbage over the years but this was below that. The plot was all over the place as was the character development. A group of friends goes up this mountain area to explore some ancient markings when some strange things begins to happen. The mountain starts taking over and one of the girls becomes “infected”. She starts killing everyone and infects another camper. The move is just all over the place and way too predictable. There were some bizarre erotic parts to it that was very strange similar to Splice. This movie was far from being scary. I have a hard time watching something when I keep wondering why they don’t leave. Don’t watch it!
