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.
Why have fun? :) Actually that’s fair, I hope the answers you are getting provide some insight and aspects to consider.
In a way, what you are doing asking why people would discuss such topics, is not too far as an idea from someone asking why one superhero would win against another or how a lightsaber would work against some fictional material. It is about sharing and discussing ideas that are or can be interesting.
I do get some insight as others in this post seems to get my point and explain WHY they think it’s interesting. I’m well aware that people have different interests.
