In an action film, you’re guaranteed a showdown here. In a courtroom drama, here comes the disruptive, sky-punching cross examination that leaves the murderer in a tearful confession. In a love story, the man runs across the tarmac, stops the taxiing airplane, gets on board and says to his lover: “When I first met you, I thought you were perfect. And then I got used to you being perfect, and everything was perfect, but then I found out you weren’t perfect, and we broke up, and then I realized, I’m not perfect, either. Nobody’s perfect, and I don’t want a perfect person, I just want you. Let’s move in together. I’ll sleep on the wet spot. You can keep your cat, I’ll take allergy medicine. And when you’re a hundred years old, I’ll clean the shit out of your diaper.”
And then, of course, the old woman and/or large black man seated next to the love interest looks at her and says, “Well, what are you waiting for? Go to him!”
Why this strange reaction from old women and large black men? Because the protagonist, on whatever scale, is now a world-altering ninja."
