Query: Derailed? Nearly...

In Derailed, the main character, played by Clive Owen, is a man under a great deal of stress. It's believable that he would meet someone like Jennifer Aniston and have an affair. What's more difficult to swallow is that he would go to such great length to cover his tracks instead of just coming clean with his wife.The acting here is probably the saving grace of the film. Owen and Aniston are great, and the rest of the cast is suitable, even if the nasty Frenchman is a little over the top.The script nearly wrecks the whole movie, trying to out-plot-twist itself too may times. In the end I was more confused than anything. Final grade: C-
