I have no idea what the writer/director was going for in this movie. It's not scary, first of all. Second, it's so slow and disjointed that it's boring and nonsensical. Did most of the movie get cut? Because there was such bizarre cuts between scenes, like one scene you see a boy hunting and then suddenly his dad appears out of nowhere. I'm worried that the director was using a bootleg copy of a film editing app on a really old cell phone.
There's absolutely no explanation or dialogue to describe what is happening for the first half of the film. The "scary" part is a black mist that randomly appears, a guy that goes catatonic for most of the movie, and a woman in a well. Oh wait, two women in a well. This movie was a waste of time, and just confirms that there's no end of money for mediocrity. The actors are all fine, they make the best of really bad material.
Scorsese would weep if he watched this.
