Not exactly groundbreaking but certainly enjoyable - as long as you don't mind found-footage films.
This does well to build the growing sense of paranoia and doubt (which leads on to mistrust and accusations) between the two leads, while not forcing in too much shaky-camerawork.
Minor gripe: the glaring red eyes of the 'devil' are just too bright. Too clearly seen.
What made Blair Witch so enjoyable for me was that you could never quite say categorically what the peculiar noises in the woods sounded like.
Here the sounds emanating from the sinister entity dwelling in the woods sounds very much like the grumbling of a territorial lion and the eyes/lights are just too clear - and clearly not a crane.
Ive seek positive and negative reviews of the ending. For me it felt tagged on and rushed, so I was slightly puzzled at it, but overall a satisfying outing.
It's just a shame they didn't run into a drunk Glaswegian terrorising the Scottish Highlands during their hiking trip there - now THAT would be truly terrifying.
