I generally tire of "twisty-turny" plot lines after awhile but this movie really kept me tuned in. I was happy to see Hugh Grant given a turn at a challenging, complex character role and he did an excellent job handling it. All the characters were well-developed and engaging. If I have a complaint it is with the "too loud" and overbearing sound track. I wish movie makers didn't think they had to try to heighten suspense this way ~ all it does is make it harder to pick up the 'mysterious' plot clues that keep a person wanting more. I'd love to see a sequel. One of the better movies in a year of pitiful pickings.
