Season 1s are great, setup, some payoff, a bit of lead into the overarching story. Then season 2 to X. The heroes win and then lose in the final episode, cliffhanger to next season. People get bored. Final season is announced and they wrap up the show.

@delitomatoes Many sitcoms have an overarching romance arc between two leads that gets stretched out for eternity. I don’t know how much I can vouch for “The Office” handling other storylines, but the getting Pam and Jim together 1/3rd of the way through the series, and then not having them constantly breaking up and dating other people and then getting back together (like Friends) was a real breath of fresh air. The show really proved they could survive as an anthology without having the main romantic arc to fall back on. Of course, later on they introduce serious romantic arcs for other characters.
I don’t look at it like an overarching plot so much as anthology. Character A and Character B have chemistry and should be together but it doesn’t happen. It just happens that there are several stories that involve that failure.
