Let's talk sound.
The audio for this movie was terrible, and here's why:
1). The quality of the audio didn't change dramatically enough while switching from different mediums (drone, DV cam, head cams, HD cam, etc). The camera quality changed, but the audio remained consistent? I can understand not wanting to mess wth the audiences ears too much, but they didn't seem to have a problem doing that with shaky footage and camera changes
2). Every sound they heard in the forest involved the bassy BOOM. This included the stinger sounds to set ambience, as well as any time the "witch" made a noise in the woods, which brings me to #3.
3). WHY did the witch(es) sound like bigfoot when they were in the forest? Part of what was great in the original is that the witch would throw rocks, scream, and breaks branches, but this time around she sounds 15 feet tall and can knock trees over no problem.
4). There were actual scary music cues in a film that is trying to play itself as FOUND FOOTAGE. There was even a point where Peter says he hears something, and you can't tell if he's hearing the music cue or the music cue is for the audience and he's hearing something else.
