I remember pointing out to someone when we left the cinema - I watched this back when it came out - once also since - that the Omaha beach scene underplayed the seriousness of the problem the US soldiers had there (yes it was a specifically US beach landing - Gold Juno and Sword were separated from Omaha by Utah beach - the other american one - and 3/4 of the ground troops from D-day onwards *were* american to be fair)).
On the real D-day it was by far the toughest of the beaches for various reasons (armour sunk offshore landing the wrong place - fresh panzer division arrived on the scene the day before or summat - landing craft going to wrong place etc.) - the soldiers were mostly pinned to the surf-line for about 16 hours iirc. So I have no problem personally with the americans taking credit where it is actually due - they got the brunt of the casualties that day for mostly that beach - kudos for taking it at all. It was pointed out to me that they had to make some allowances for dramatic effect however - a full gruelling 16 hour marathon was probably not required
However, having seen it twice - it's a overall a reasonably pointless film for me - mostly just about the - yes extraordinary - opening sequence really and general war-is-bad-mmmkay type stuff.
Actually thinking about it now, maybe I'm now benumbed to the war-is-bad message in such war films. I used to like stuff like Platoon, Apocalypse Now and such but more recent war films like 3 Kings, Thin Red Line, American Sniper - what's the one with Matt Damon as a bomb disposal guy? - haven't really done anything for me. I guess the special effects of blowing people up get better but I got the war-is-bad soldiers go mad/do evil things under hellfire conditions message some time ago... ho hum.
