I can't say that I hated it, but I couldn't get past Tom Hanks. Of course, in the end, the point was that Hanks wasn't a "War Hero" but an ordinary guy who was unwittingly put on a pedestal by his subordinates and in "reality" was just a school teacher but come on, this guy was wearing dresses on a weekly basis with Peter Scolari in Bosom Buddies.
And besides, in general, when Tom Hanks "acts", it is very obvious that he is acting. I never thought he was that good of an actor. The rest of the movie was, IMHO, pretty good.
