"Jodi Foster's intense yet subtly nuanced performance (which builds on a fair amount of post-9/11 paranoia) encompasses all the shifting emotions required to grab and hold your attention."Peter Saarsguard is also very chilling in this, borrowing some of his skill for being a horrible soul that he honed in previous roles such as in a movie with Hilary Swank seven years ago.The story lacks some beleivability, and fails to explain the terrorists intentions and modus operandi.
