In which category fall episode-adaption series that also end where the episode ended. Even if it's a cliffhanger in the big picture but got a distinct plot-arc on its own, too.
Sorry, Michael, I can't visualise what you mean by this. Most episodes end definitively. Unless it's a two-parter, of course, then the first part would have TBC. And I've read that second sentence five times now and am no closer to understanding what you mean by it than I was the first time.
Maybe it's just getting late. I'll have another go tomorrow, after some caffeine.
