I watched the four hour WW2 Guadalcanal Campaign documentary on YouTube on the Kings and Generals channel.

It’s basically a bunch of battle videos combined in order.

Some of the writing is not ideal, and I know from familiarity with the subject matter that there were some errors and omissions. However, what I really like about the Kings and Generals visualizations is that instead of throwing old war footage or a talking head or some 3D render up, they spend their whole time looking at a map and showing how things play out on it, which provides for a much more useful sense of geography. Almost every one of the handful of war documentary makers that I really like does the same thing.
