I forgive you; that's because you don't understand the depth of my love for action movies.

If you want a less hyperbolic simile, it's like asking a professional wine connoisseur what their favorite drink is. It's a complicated answer, and the favorite depends on what you're trying to accompany and the specific mood you wish to invoke. Even a less experienced wine drinker might have a favorite red wine and a favorite white wine, and they have nothing in common other than that they are wines.
