Obvious spoiler warning, but the plot twist just doesn't make sense to me. Marie is the killer, but she was there pleasuring herself with a severed head BEFORE arriving with Alex? She's inside with Alex when her brother is shot, but is also the one outside shooting him? Who does she beat and strangle to death near the end of the movie? She separately drove 2 different vehicles from the gas station to the forest near the end of the film? That doesn't even make sense. She's seen in the same frame as the "killer" several times. There's literally no explanation for any of this, making the "twist" hold next to no weight. If your explanation is that Marie was imagining all of it, then nothing the audience has seen really matters at all, so what's the point? All in all: uninspired, lazy, and perhaps most egregiously, boring.
