At first I thought it must be written by a woman, because of a dark, mysterious man who ends up in the midst of a mother and daughter who live alone... You don't know what to make of him. At first he's just there and no one can speak of him. There is sexual tension. Then he begins to pry deeper into their lives, more sexual tension ignites, then jealousy and then just plain strangeness. At this point the plot can have gone anywhere, but it really doesn't do anything interesting. There is a twist at the end that revealed to me nothing more than that my instinct that it was written by a woman was wrong. The writer must obviously be a man, I thought. And one who must think he's very clever, and wants to think he's in control of his characters, but really he doesn't know what to do with them and he never created a decent plot for them anyway... in the end he unravels them into a morass and leaves them that way. Some people might like this movie for it's suspense, but it just barely kept my attention and I was disappointed with the anti-climactic ending. It was made around the same time as Chloe and has a similar theme. The difference is that Chloe was written by a woman, so it's a woman rather than a man who is tasked with manipulating the other characters.
