There are tons of historical war films much better, Saving Private Ryan, Gladiator, The Last Samurai, Glory, Black Hawk Down, Braveheart... and Kill Bill VI & II. LOL
Gladiator is an awesome movie, but it was NOT historically correct on many counts. The usual trend is: If it's historically correct, it's boring, if it's exiting, it's not historically correct.
Braveheart....... I'm not even going to start on the historical mistakes it made.
Black hawk down - It was pretty accurate, but the story of Mike Durant was incomplete (didn't even show a lot of it). The death of humvee m-60 gunner Pilla wasn't ephisized, thought it was really the first death of the conflict, and really important. Smith's and Grit'z death's were accurate though.
