My general thoughts (spoilers)
1). I think the movie overall was decent, C+. A lot of the negative reviews against the film are provoked by a general tiredness with found footage movies, not a specific criticism against this film. I like found footage movies, so I didn’t enter the movie predetermined to hate it, as the critics did
2). The biggest flaw in the movie is that some parts are too explicit and corny. The ending, for example, shows the demon driving a car, which appeared more comedic than horrifying.
3). The best scares in the film were subtle. Perhaps the best scene in the film is when the characters talk to the postal worker, who said “Those guys aren’t Amish.” At that moment, you could feel a sense of uneasiness.
4). I appreciate the way the movie allowed the protagonists to survive. The black guy was quite brave to enter the hole to save his girl, and as a result, I feel he (and his girl) deserved to live. If any protagonist had to die, the big dude was the right one
