I may not be an American, and not even like anything about war, but this show has me hooked and the plot twists, authenticity and values keep pouring out of this show, making it so real. Few shows today on air can make the same claim.
Perhaps what I like best is the characters. Like many other shows I like (House, LOST) it's not always what they do or if I agree, but rather how they do it and the reasons behind it.
I really do hope more people discover this gem of a show, especially now when so many other shows are awaiting new scripts since the strike-ended; and really besides the tacky 'real shows', this is refreshing to watch, and is more real.
