The thousands of frames that make up a TV show are edited together into an episode in order to tell a cohesive story to the audience, so it's not really fair to make assumptions about the show based on a single frame.
But the internet is full of people with really strong opinions about shows they've never seen, and if you post a single frame screenshot from a show and ask them to explain what's going on they'll answer.
And sometimes their responses actually sound like an episode of the show, which means these people are lying when they say they've never watched the show or the show was written via algorithm.
