Don't assume a scary thriller as I did after watching the trailer for this movie. It wasn't scary at all and was too slow paced to consider it a thriller. The storyline and acting were lacking and dull.
I'm not sure if the actual actors selected fit the movie though. I would have gone with a different casting. Ben Kingsley might have fit the role of a dark frightful serial killer, at least so it seemed in the first five minutes of the movie. However, as stated earlier the movie went a different direction. Aaron Eckhart, who plays the other main character of the movie, is bland. I found myself more irritated at his character more than anything else. The forced relationship between him and Carrie-Anne Moss, his partner seemed to be thrown and mixed together just to add some substance to the story.
This won't be the worst movie you'll see far from it, but wait until you've seen all the other movies you want to see. This one can wait. I'd say rent this one if it's the only one on the shelf.
