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.


Which is exactly why it can be interesting to discuss?
Edit: to add to everyone else saying “it’s fun,” it’s not just about that.
For me, it’s important that fictional stories (particularly outlandish subgenres like sci-fi or fantasy) must have internal consistency, unless I lose my ability to suspend disbelief.
Sometimes that means checking that the internal logic the author is using makes sense and stays consistent.
Absolutely 100% agree. Internal consistency is where the key is. And in order to have that consistency, the rules for the worldbuilding must be relatively clear and well established. It’s really interesting where a few fantasy/scifi creative ideas can take you if you start unraveling the consequences those ideas have on the rest of the created worldbuilding.
And conversely, there’s nothing more disappointing than a promising sci-fi or fantasy story that doesn’t care about internal consistency
