Great series. Mostly because it is largely uncensored and the crew actually get to speak their minds. The damn thing even shows a disciplinary session where a sailor gets punished for having alcoholic beverages on board the ship. You never see that in this age of political correctness.
I spent many a month on a navy assault ship and seeing the series on TV brought back many many memories.
What I found rather amusing was the fact that a lot of the sailors openly expressed their views on the war in Iraq. And it was none of the rehearsed and canned views about fighting "over there so we don't have to fight them over here" crap you hear from some PFC who knows SgtMaj is standing over his shoulder.
Highly recommended this series is. Highly recommended.
