As a concept, even with the horrible twist, I was terrified. And I’m mostly leaving this review just to give myself closure that this is just a movie because I keep putting myself into the movie, as a movie the holes were plentiful and the concept was just weird.. also SPOILER I heard that the point of the movie was that the monster can’t hurt you so it has to make you hurt each other.. but it literally kills 4 people and has gas that makes you EXPLODE! What kind of analogy is that? Bad movie, I have a personal vendetta, please stop haunting me.
