Deus Ex Machine Gun

When discussing how awesome Children of Men was, Tina pointed out that it had some flaws, like a scene where someone is utterly defeated, the bad guy cocks the gun, all hope is lost, and rat-a-tat-tat come the bullets from off-screen. I said "Oh, you mean the deus ex machine gun?"** and then spent the rest of the evening terribly pleased with myself.

For those without a background in dramatic theory.
