I LOVED the Wire, so I was really looking forward to GK. Now that its over, I have to say that it was certainly good, but not as phenomenal as I expected. The combat never got intense enough for me, and there wasn't enough of it. Other than that, it was better than every other crap series produced for television.
I'm very interested in learning more about Lt. Fick, who seemed like a fantastic platoon commander and apparently wrote his own book after leaving the Corps. Generally speaking, the non-coms seemed dedicated, talented, and relatively considerate of the Iraqis, while the company commanders and Captain America (a captain commanding a platoon for whatever reason) were all made to look completely incompetent and downright dangerous, except for the captain who punched Encino Man during the football game (I can't remember his name). Godfather was a cool character even if he ended being an asshole regarding his treatment of his officers and the natives.
If the series was accurate, I am more disgusted than ever with Bush and his reckless, ramshackle foreign policy and the effect it has had on our military and the rest of the world.
