The Pacific >>> BoB in case that wasn't already mentioned ITT
Watch both if you haven't seen them, though. Pacific is really really violent.
The Pacific makes for a worse plot, in the traditional sense, because so, so many of those poor bastards got killed so quickly. A far, far worse experience than what the guys in Europe went through. Literally hell on earth. The guys in Europe at least got to try and bang chicks and stuff....the Pacific was just one big suck.
I tell this story a lot, but my grandfather was wounded and sent home from Guadalcanal relatively early...he was stabbed by a Puerto Rican guy in his unit over a dispute. True story.
