I liked BoB a lot -- better than Saving Private Ryan. Didn't like the end of SPR at all.
I thought BoB showed a good balance of the camaraderie of the troops, the heroism and the horror of war.
Obviously, as a senior citizen woman, I've not been in combat myself (though my son has), but from what I've heard from those who have, and what I've read, it's very realistic.
I love it. I love the depiction of Winters.
