As far as such "psychological" whodunits go, this one had an OK story-line based on a realistic premise. Unfortunately, the acting was poor, and here I am particularly referring to Luke Wilson in the main role of Preston. He was never really convincing as the "cheated husband" out to avenge both his wife's murder AND the fact that he was cheated in the first place. He tried too hard, as I think someone else also pointed out in a previous comment. Dennis Farina was fair enough in his role as the private Dick (though clearly stereotyped), and overall I liked the way Norman Reedus played the Jonathan character (despite cozing up with somebody else's wife, he turned out to be not exactly a 100 per cent nasty person but actually an interesting character study in himself). Although having said that, there were a couple of things he did over the top ... like setting himself on fire, and walking around with the crucial video-tape in his pocket all along(!)
