The Borderlands, The Mirror, now this. Though this precedes the other two by two years.
Understated and creepy. Left just enough unexplained/to the imagination. Which is how I like my horror.
Characters and dialog chiseled and sculpted with a light, deft hand. Lead character felt like a real bloke: affable, stable, reliable - someone you'd trust in a crisis; yet at the same time has a hidden fuse, a darkness, a mania. At times you're scared for him; at times you're scared of him.
The movie reminded me of and made me miss growing up listening to ghost stories on radio on Saturday evenings, with my mother finishing up the dishes in the kitchen the next room over. It has that kind of 'real' feeling.
If I had to bone-pick, the shifting in and out of found-footage pov was a little jarring. There's something about the purity of a commitment to found footage - well-executed and credible, of course. The last act was also a bit too jumpy and jumbled.
I also like the cover poster with the cave better. (The one with the kid looks low-rent.) They should market the film with that one.
