I've watched hundreds and hundreds of documentaries on military history and I've read as many books. From a Historian perspective, you probably won't like this series ... it's not a dissection of strategies, exploration of leadership styles, or meticulously detailed analysis of anything (the thing we historians love). What this is is simply this ... it's an effort to give a voice to some of the last living WWII combat veterans before there are none left. That's it ... and that's okay. Sure, this series could have been told with half the number of episodes (a lot of the footage is repeated) ... but the producers/directors are trying to paint a picture and the footage is only one color on their canvas; and like a painting, colors are often repeated.
What this series is ideal for ... is the modern generation. It's short, visual, and emotional that introduces more WWII history than is currently taught in the public schools. Every High School should show this series ... with signed parental authorization, of course (ironically, boys the same age today would need permission slips to watch the movie ... whereas 70+ years ago, boys of the same age, were living it); that is, if you can break them away from the Kardassians, Survivor and Facebook.
