Rambo: First Blood Part II (1985)

This is what happens when you let James Cameron help write your screenplay. Rambo, now literally a one-man army, gets sent back into Vietnam on a half-assed top-secret covert mission that enables him to crank the action genre clichés to maximum, and beyond. He creeps and plods through a jungle that was better lit than my back garden on a summer night, before initiating a maiming montage.
It was even worse than I remembered. The only saving grace was the almost complete lack of Arnie style one-liners.
