Great if you pay attention I'm gonna be real, this movie had me wanting to turn it off 20 minutes in. I'm glad I didn't, as I watched the rest of the film and I can genuinely say it had me feeling any emotion you could think of that doesn't contain any happiness. The interpretation of this movie could go two ways, either the boy is in a coma or a demon has transported him to a horrible place just for fun. For me, I interpreted it as Kevin being in a coma after he falls down the stairs in one of the opening scenes. Everything that happens to him after is just his brain messing with him. Particularly the knife in the eye part, the "572 days" part, and the "demon" stabbing him over and over near the end. He's getting invasive surgeries, and has been in a coma for 572 days. At the end a figure tells him to go to sleep. He dies. This story, while it is sad, drags on at times and would definitely seem boring if you arent scanning everything at all times. Just for the storytelling and the concept, this movie is excellent and one of a kind, and kept that creepy ambiance throughout that had me frightened for the entire duration once the boredom that the first 20 minutes caused faded. In my opinion, this is an incredible film.
