The people asking for realistic consequences for action scenes in their media don’t even know what they’re asking for
Yeah combat in fiction is unrealistic. It has to be. Adding realistic consequences to fighting and action scenes in media would completely inhibit the ability of the story to tell a story.
The character gets shot. In a story, they continue to fight while muscling through the pain and win against all odds. In real life they can’t staunch the bleeding and they die of blood loss in ten minutes. Does realism improve this story?
I’m not saying realism can’t enhance some stories. Shows like The Pitt wouldn’t work if they weren’t so true to life. There’s genuine value in prioritizing realism in a show like that. Prioritizing realism in something like John Wick would just result in a worse, unsatisfying story as John Wick becomes permanently crippled after the first movie and has to spend the next two films slowly recuperating and doing physical therapy to get back to just a normal keel of physical activity.
