If you enjoy a suspense driven story and a lot of good actors then this movie is definitely what you are looking for.
I will say that I figured out a big chunk of the story about halfway through, but that’s because of my knowledge of certain areas of history. Other than that the story was well thought out, fairly original, and interesting. The actors, especially Denzel Washington and Clive Owen (though you do not see much of his face), were fantastic. There is a lot of back story and motives that they leave to your imagination and of course there are little “easter eggs” thrown in throughout. It was a very enjoyable movie to sit through and I will probably watch it again when it comes out on DVD.
