Dang good episode. Slow at first, but the intro sequence with the charcoal pencil splintering like shrapnel disposing of the idea that something as serene as doing a drawing can foreshadow violence was foreboding.
Interesting in how they went 180 degrees from Generation Kill which focused so much on collateral damage and the mental states of 1st Recon and went more with the violence of action culminating in the .30 cal gunner's starring out at the dozens of soldiers he had killed. The friendly fire incident got what, 45 seconds? If something similar had happened in GK, they would have spent half an episode on it.
In GK, the book, one of Alpha Company's first surrendering groups of Iraqi's whips out AK's and fires on the Marines. In Nasariyah, Bravo has an incident where they see men firing AK's and carrying RPG's while holding children as human shields. Did they show that evil side of the enemy in the mini-series? Nope. They did not fail to show that side of warfare on The Pacific.
I did like The Pacific's first episode. I did not like the way Generation Kill was handled. There were a series of tough battles that the public needed to be reconciled with in the planned second season of GK, but the men and women who fought them got shorted because of what I believe were short-sighted or biased editing of the story of OIF to make a point.
