OK, I'll discuss. We amphibians have a keen sense of what constitutes a cliffhanger. Actually they are easy to spot...they always seem to smell of goat.
First, M*A*S*H. There were no cliffhangers in M*A*S*H. As horrible as the Korean War was, it really had nothing to do with the TV comedy. It was merely the background wherein a dysfunctional field hospital played host to an ensemble of goofball surgeons and nurses...all for laughs.
Cliffhangers may occur in literature or motion pictures at any interval. A weekly chapter release does not eliminate the presence of a cliffhanger merely because of the short wait for the next installment. When I was a kid, all the kids went to the Saturday afternoon movies at a neighborhood theater. [Admission was 12 cents; you saw six cartoons, a newsreel (the Korean War was the big news), two feature movies (at least one was a western), and a serial thriller. If you liked the show you could stay and watch it again free of charge.] My favorite serial was The Black Coin. The serial had a new episode each week and each episode ended with a cliffhanger.
There are varying degrees of cliffhangers found in literature and cinema. Most authors of serially-released stories use them to keep the interest of the reader. Rather than arguing endlessly about what constitiutes a cliffhanger or whether the latest chapter contains (or end with) one, the author should, as I suggested earlier, just suck it up and get on with writing the next chapter so that the latest cliffhanger, if any, can be resolved.
Thanks, Cliff, for the opportunity to comment on this burning issue.
