I'm sorry to say this was a really bad movie. The plot was all over the place you didn't know if they were going crazy due to demons, if they were going crazy due to mushroom spores, if they were going crazy through being separated from human contact for so long, or if they were infected with the virus that made them go insane. Really really just all over the place and the ending was disappointing and left you questioning what you just saw in not a good way.
