In novels, yes. But TV shows weren't always that way. Go back just twenty years and look at show made then, and you'll see what I mean..
Good point. I mean, look at THE AVENGERS (Steed and Emma, not Tony and Bruce) or PERRY MASON or THE LONE RANGER or COLUMBO.
They didn't have beginnings or endings. Didn't hurt them one bit.
It simply depends on the show. Some shows have arcs. Some shows are more episodic....
Exactly. My original comment was specifically directed at the frustration of starting a serialized show that gets cancelled before its resolution.
