Honestly, I think it's overrated. Yes, I know some people enjoy watching it and everything and most football fans seem to go insane over it, but I don't see the point in sitting around watching other people play sports. The closest I've come to enjoying it was the very short stint I spent on the football team at school back where I'm from. But I had alternate reasons for joining aside from liking the sport though.
TL;DR: Football is overrated and not everyone enjoys it. The ones that do are just exceptionally loud.
