Why do fans like continuity so much?
I don't read individual monthly/weekly issues - mostly trades. And only those that become available. So most of the times I have no idea of what came before and what came after. Most of the times, it's not really necessary to know that. As long as you know who Superman is and the main characters in his series, you should be able to pick up a Superman trade collection and be able to read it (except maybe for the Blue Costume years). You might wonder about the weird mullet or something or how come he's working as a telecaster (as opposed to a newspaper reporter) depending on which era it's from. But in general things should make sense.
Does the continuity need stem from waiting for the next monthly, where during the wait, you start to add up clues and try to define the storyline of what needs to happen in the future? Or is it because of a need that we all have to know what is the beginning of a story and not join a story mid-way? Or is it about knowing more about the superhero(ine) that you follow than the average fan?
Idle musings - but there's the other need also that is in all of us and that's to listen to the same story again and again. I see it in my young neices/nephews all the time. It doesn't matter that they've seen a particular DVD 15 times, they will happily watch it all over again. Similarly I read the same trades again and again (or read the same book again after a bit of time). For superhero(ine)s, I think I am comfortable reading take-after-take of the origin story - some of which I'll like and some which I won't.
Things are somewhat contradictory about how/why we want continuity in our stories.
Thoughts?
