This is a very tense and entertaining film. The acting was really good and no wooden characters. The idea of having cameras all around the house inside linked to a company is creepy in itself. True security would be decent locks, and a guard dog! While the story is not very original, there were some interesting scenes. The villain was just creepy at the very beginning. The heroine wasn't in the least suspicious of anything when her creepy admirer kept showing up. The fact her stalker worked for the security company that installed her cameras should've been red flags. It made no sense that he was promoted.
