My one complaint so far is that they COMPLETELY ignored and omitted the efforts made by the Cactus Air Force to help hold the line. Yeah, I realize the air war isn't part of the story they're telling, but there wasn't even mention of them in Tom's voiceover in the prologue. Savo Island got a mention, so they could have at LEAST informed the audience that with naval support gone the CAF was the only thing holding back the IJAAF and IJN while the Marines held out on the ground.
