Greenwood is a good actor with excellent screen presence, and this role gives him a chance to shine. Although the movie has some crudities and unlikely minor plot devices it also has numerous strengths, best of which is displaying the government being capable of saying and doing most anything not just in a crisis but as a way of life. A 2004 movie based on what's happened since 9/11, the numerous government responses and actions and general thinking-out-loud deliberations are all too believable. This is not just background to a story of terrorists taking over a nuclear power plant, but actually becomes the story. Recommended, but this is definitely not a feel-good action movie. It takes you places you really don't want to go, but it leaves you with a lot to think about.
