I often come across posts where people are discussing the logic of a movie or comic book. An example could be Star Wars, where they discuss how a light saber works. Or which superheroes would win in a fight against each other. To me, it seems pointless to discuss such things as it is fiction. Just an insight into someone else’s imagination.
It’s an enjoyable way to engage with fiction and think critically. Everyone in the debate knows lightsabers aren’t real, but there’s established in universe rules and community-agreed principles you typically frame your arguments on. This can keep a piece of media alive for fans, if it was just about watching movies and not really examining them then there wouldn’t be much reason to revisit them, which I feel would be a shame after writers put so much work into creating a universe to explore.
It can give you a good reason to continue to engage with the content, or engage with a community of people who also enjoy the content. In my case watching Star Trek is fun and all but not if I’m just mindlessly consuming the show. Looking at a ship’s engine, liking engines in real life and saying “I wonder how that thing would work” is a good mental exercise, especially when you’ve found others who have the same questions.
