There is not much to say about this film actually. The plot is derivative and predictable, with some silly moments. The first hour of the film is filled with nothing to interest you except for cheap scares and false climax, and even those you can tell from a minute before happening.
Julianne Moore's role reminded me of her performance in Red Dragon, which was terribly boring. In this movie she is OK but she seems to be able to give more, and was impressive being the eccentric sexual artist in The Big Lebowski. I guess just dont do anymore investigator role.
