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.



My understanding is most do but it’s the subject of occasional controversy.
