First, to anyone who thinks this is a zombie infection movie, it's not.

The Solomon family was living on their own because of their demonic heritage in the family.

The ritual of throwing food / raw meat in the wood is in fact to give it to the father who becomes a demon and lives in the woods chained (The cave hank found with the chain)

The mother made 3 rules to keep and keep Solomon Safe. The first rule is to feed themselves when they're demons so they don't attack Solomon, Second humming the song which would help them recognize it is him ( At the end mom recognize him by the humming ) Third always have ropes around him for the sake of his safety.

When Solomon met Hank, he didn't want to leave with Hank because he knew his mother was in the woods ( He doesn't get scared by demonic screams ) but he still decides to go into the woods with Hank in the hope to meet his mother

Solomon in the end witnessed his mom's suffering and decided to end her. Unfortunately, the demonic power didn't stop there instead Solomon inherited the power which gave him visions to see ( His eyes getting pupils at the end )

It's artsy and atmospheric and the actors do a stand-up job, it's even craftily filmed, but about halfway through I realized nothing was really happening, and wondered if it could be condensed into a much shorter version. By the end, my mind hadn't changed and I wondered if it should have just been a short. Then I discovered that the director had, in fact, based it on a 12 minute short, which I am now eager to watch to confirm that this thing would have made an absolutely brilliant short film.

One of the better horror, suspense, and mystery films of recent years, and it does so on a small budget with only a small cast. Some of the denser people who insist on lots of gore and explosions downvoted this because of short attention spans and wanting only flash and trash. But it really does deserve to be rated around 8, as it was by critics and the audiences that first saw it. There is an incredible sense of tension, fear, and mystery for nearly the whole film.

Spoilers: Really? Some people actually had a hard time figuring out the ending? Do they want big flashing letters or sometime telling it to them? This was so obvious.

The boy's mother changed into the monster he'd heard in the distance. At the end he discovers her living nearby, chaining herself so she wouldn't kill anyone. He comes close, angered she lied to him and left him, kills her, and is changed to a monster himself.
