I watched 6 episodes of this today (the last one is on tonight I believe) It's absolutely brilliant.
I imagine it's a very realistic portrayal of what's going over there in Iraq. The dialogue is tremendous as is the naturalistic acting. I like the fact that the fighting is secondary to all the character interaction and the day to day life of a Marine. It's quite funny seeing Ziggy from The Wire talking smack all the time. And Tony has a small cameo in most episodes as well.
I wish you could get this quality of drama in the UK.
Has anyone else been watching it?
