I guess being the father of a Navy SEAL has made me a bit jaded. The military execution was laughable.
I'm sorry - pistols just don't sound like shotguns. Then there was the grenade that rolled into the foreground - but the explosion was triggered from the left side of the screen. And what was up with the hockey-puck explosive charges that were magically slapped to any porous, rough surface and produced an unrealistic explosive force? Another question - the bad guys had attack helicopters, but they were never dispatched to chase down the lumbering pontoon plane as Stallone & company unrealistically strafed the harbor.
But wait, there's more...
The tough-guy talk was unrealistic, the film editing was pathetic. Middle school musical productions pack more acting talent than these seasoned veterans combined.
Stallone's character was nauseatingly stereotypical. Tough, silent type who is drawn into mortal danger after a chance encounter with a very average-looking chick. He impulsively sets off on a suicide mission to rescue her. He magically locates her and dispatches the thugs who are on the verge of raping her. She lives through a barrage of staged explosions and a hail of bullets. Of course, the arch-villain (ex-CIA, of course) holds a gun to her head in the climactic arc of the farcical mission. And of course, Stallone dispatches him without harming the woman. An added plus: an over-sized Bowie knife cuts through the guy's spinal cord, internal organs and protrudes 12 inches through his breastbone to the audience's delight. And of course, when the chick gets vulnerable, the tough guy turns away from her without so much as a peck on the cheek, presumably to set off on the next implausible mission.
