Ideologically, the things that fit into genres and categories are not realistic by any means. Nothing fits perfectly in the boxes the media and other conventions try to force them into. There are more than fifty shades of gray. Not everything is black or white. I’ll use my previous example of action movies. Action in everyday life is not something blowing up every three seconds, cars transforming into big ass robots, or even Vin Diesel stealing and street racing cars in your neighborhood. Action in everyday life is a car accident that blocks up the road in the morning, a fight at school that gets reenacted for the rest of the day, or even the birth of a child. These are realistic and are what can be expected during everyday life. I guess people watch action movies because even though they know it’s unrealistic, it’s nice to ponder what it would be like in reality. Cars blowing up, shoot outs, and drag racing are all cool in retrospect, but the actuality of it is when these things actually happen in real life they are terrifying. Nobody actually walks away from these things unscathed. Have you seen Fast and Furious 7? I would love to know how the hell Vin Diesel walked through flames and only had a handful of cuts and bruises. How the hell did he have a fist fight with another man, where they were actively punching each other in the face and slamming each other into walls, and not walk out limping? How Sway, how?!
