One thing I love about the movie "The Replacement Killers" is that the guns all run out of bullets at realistic intervals. There are lots of scenes of the heros/villains reloading, frequently.
And when the good guy goes marching in to the villain's most heavily guarded lair, he does it with about 14 guns strapped to his body. When one runs out of bullets, he simply drops it and grabs another -- it's faster and more reliable than reloading.
The film also violates another movie cliche: The woman he ends up on the run with (Mira Sorvina) turns out to be just as tough and competent as he is (no more, no less).
