I finally got to watch this movie and found it, while entertaining, a whole lot ridiculous. Spoilers follow. We're supposed to believe:
A). That Nazis shooing automatic weapons at a man running backwards only hit the gold miner's pan the man is holding like a shield in front of him when they can't hit the broad side of a barn the rest of the movie.
A1). That said miner's pan can stop bullets like it's Captain America's shield.
B). That a man's body is enough protection to shield another man, carrying the first man on his back, from a large German machine gun, like it wouldn't tear right through the first body and into the second.
C). That a man can stay submerged underwater for long periods of time by slitting other men's throats and breathing through their wind pipes.
D). That a man can survive being hung by the neck for hours by propping himself up on a nail through a wound in his arm/leg (not sure which appendage the nail went through.)
E). That a man can survive a plane that crashes full speed nose first into the ground by strapping himself against the fuselage.
F.) That a man armed with only a rifle that gets taken away from him right away can defeat a whole armored column of soldiers basically by himself.
G). That a man can use a pickax to snag a plane that has taken off over his head, cling to the underbelly of the plane with the pickax, lose his grip, but regrip the plane on one of the landing wheels, then use the pickax to break into the plane from underneath.
Good ridiculous fun. This movie sees your Quentin Tarantino and raises it a Sam Peckinpah.
