I disagree, but different people like different things.

I can't argue with that. I did used to prefer longer story arcs, at least in concept, but over time I've realized it's become a facilitator of lazy story writing. It takes a lot of tact to wrap on up an idea into an episode or two, and I think that's a good constraint for writers to have, whereas a story arc spanning multiple seasons can quickly turn into a bait and switch. I've seen too many arcs start with interesting concepts that get dragged out to a point where they completely trail off, leaving me wondering why I'm still watching. Modern TV can be a lot like the ol' boiling a frog in a pot of water. Only it's not so much people are getting hurt as their time is getting wasted. It's not that I don't appreciate arcs, and I know why people want continuity, but too much continuity over concrete ideas has lead me to leaving my TV mostly off this last year.
