I thought this movie was genuinely scary. The big problem though is that the movie restricts itself. The basic plot is that basically people invade a couples house. That's the problem, you're stuck at the house the whole movie and there's really only a few characters and doesn't seem like there's a lot of dialogue because of that. There's a tiny bit of back story but it doesn't factor into the rest of the movie really. The movie is pretty scary at the start but once you get to the middle you're thinking these people are stupid.
Rated 14-A (ONT) R (USA)
P.S. I Called It!: The movie reminded me of the Manson murders and I said that and sure enough Wikipedia says that the director says that he was inspired by the Manson murders book and his childhood.
