Pure action movie, unadulterated by any but the sketchiest of plots. Excellent job. A heart-pounding adrenaline surge from beginning to end. Just when your pulse rate gets a chance to recover to high normal, off it goes again. No nuanced performances here–all the characters, even David Strathairn's (one of my favorite actors), are pretty much one-dimensional. But it's dead serious about being a explosively high energy action flick. No cute stuff, no unbelievable tricks (unless you count the number of times Jason Bourne should have died or been rendered a vegetable but didn't and wasn't). This is one heck of a roller coaster ride.
