With my intense passion for the issue of dependency on foreign oil as a strategic threat to Western Civilization (see Syriana, The Prize,the Coming Economic Collapse and Crude Awakening), it's probably no surprise that I liked the premise of The Kingdom
To me, of course, the story is highly plausible. There's a lot of action and I found the storytelling to be quite solid. Good elements of creating empathy for the main characters and of tying together various plot points.
The last scene is jarring for its veracity. Silent, subtle, but poignant.
