Band of Brothers was such a special animal in that E Co/506th was involved in so many things, you could follow just that group and have a fantastic story.
The Pacific is good, but I'll echo the sentiments that they're moving a bit fast over some big stuff. It feels very disjointed, and I'm still not 100% sure who I'm following aside from "Lucky" and obviously Chesty Puller. Basilone I caught, but the battle scene was really hard to follow. I hope they get a chance to get deeper into the characters.
Maybe they'll throw the Navy a bone besides being corpsmen, cooks, and boat drivers?
