Not really interesting, and that's not helped by the rather untalented (or should I say uninteresting?) Matt Damon who plays the title character who reveals his company's price-fixing activities. It drags and drags, and really paints a bad picture of this informant guy to the point where you (I) end up hating him. The plot is overly complex, and the director attempts to keep it light with a comic touch or two, but it doesnt work. I seriously didn't enjoy this, even though I have to admit that it's well-made (direction, sets, camerawork, script).
