I was disappointed with this film. It spent a long time setting the scene only to devolve into yet another 'crazy killer in your house' story. I'm starting to wonder if these films are funded by the NRA in an attempt to keep Americans so terrified of, and obsessed by, the notion of home invasion that they'll run to the nearest gun shop before the credits finish rolling.
Motiveless malignancy, unless brilliantly written, is tiresome and frankly, just nasty. Lazy storytelling: no points to make, nothing to say about the human condition, no attempts to empathise with or understand the characters.
Yawn.
