The way they just shoehorned in the Tuskegee airmen, especially after how they were so prominently featured visually every week in the opening credits, was my biggest disappointment. They should have done a different series for them or featured them with their own side story throughout the series. They showed up very late out of nowhere, then disappeared, then one is shown captured, the end.
Overall a very enjoyable series, definitely better than Pacific, though it had some problems. It probably had a more limited budget for the times. The script seemed bloated and limited at the same time. It's like they had too much material with the original basis for it to be one feature film, yet not enough for a mini-series, so they shoved in some other material to stretch it out. A lot of the details were hard to follow the way they rushed through so much of it. The visuals were amazing, the characters were very good, so there to was enough to like.
I'm going to have to watch it again someday to get a better feel for it, but unfortunately I can't buy a freakin' hard copy of my own to watch at my leisure when I feel like it.
