Pretty disappointing. They spend so much time at the beginning with the kid hesitating to go into the house that it's almost comical, and it gets incredibly boring waiting for the monster to show up. The first scene is a long exchange in a car between father and son that seems to last forever. I read an interview with the director where he talked about using practical FX, and there is a guy in a suit for the monster, but then they did a lot of CG effects on top of it to make him move quickly. It really doesn't look very good at all. The real problem is the monster doesn't do anything until the end of the movie, and the dad is another asshole who puts his kids in harm's way to make them face their fears, but it's going way too far. Plus, early on, you get a scene with the step mom in a washer room that ends so abruptly I didn't understand how she got away or what happened. It's just a mess. I liked the gore at the conclusion, but it was such a huge change from the rest of the film, and when they're in the monster's world, the fact it's low budget becomes horribly obvious since the set is way too cheap and small.
