For a long time WW2 history nut, there really wasn't any new ground covered, and I was surprised since they've talked about all the footage they went through, that I didn't really see anything I hadn't seen before.
For someone just starting out though it was very well done.
It covered pre-war through Guadalcanal. So essentially 39-42 with the focus coming out of 4 towns where they did interviews, Luverne, Minnesota, Mobile Alabama, Waterbury, Connecticut, and Sacramento, California.
The fuss caused when the Latino community complained about lack of coverage in the documentary was a section added to the end of the show where they talked with two Latino soldiers out of California who both served with Carlson's Raiders.
