SPOILER ALERT, DON'T READ FURTHER.
I'll try to not spoil the movie for those determined to see it. so please don't read further but the movie made me mad.
I thought the movie sucked. The Army was like the Huns, the final battle scene was a joke (one entire mechanized infantry unit couldn't figure out that just maybe you don't have to advance to the front of a tank but might just surround it.)
Getting out and shooting it out from an open position with hundreds of advancing germans , uh OK..
.and the "nice" Waffen SS after watching his company decimated was such a stretch. Not to mention 3 shots with a Mauser including a chest shot and being able to talk as opposed to drowning in your blood like a normal human.
The love scenes....the whole thing was a joke. My daughter dragged me to this cause she wanted to see Clint Eastwood's son. When we left she shrugged and said, 'might been better to see Gone Girl, huh?"
Do yourselves a favor, wait till it comes on cable or netflix. The tank battles scenes were good, but the rest was just lame.
I thought the movie was excellent despite agreeing with your assessment of the plausibility of the final battle. However, I was able to suspend disbelief and go with it.
IMHO it was not as bad as most action movies, like Mission Impossible where Tom Cruise leaps off a speeding train and violently collides with a helicopter without any apparent injury. Or any Jason Bourne film where the protagonist can effortlessly take out a legion of armed, trained combatants with his bare hands.
I think Fury is as close to an old school WWII film where our side are the good guys as has been made since the Longest Day.
