worst has to be Pearl Harbour... my god!
ben affleck and matt damon, or whoever, go up against 70 japanese planes in the sky.... yes, 2 against 70 - and win..... oh, that film was terrible, if you werent cursing it for being shit when you was watching it, you were laughing at just how ridiculous it was and do they actually expect you to believe that. awful film. destroy it.
the best war film is without a doubt platoon - followed by full metal jacket, the killing fields, and the TV series band of brothers.
