It's not really their fault at this point, though. People expect cliffhangers and get mad when they don't get them.
Yeah, it's a trend that's creeping up in episodic television now too. So the cliffhangers have to get bigger and bigger.
You know what's funny? I never watched
Dallas but "Who shot JR?" is something that I just know because of how unprecedented that cliffhanger was. All the mythology surrounding it - the fact that they filmed fake endings so that there would be no leaks - including the fact that The Simpsons did a parody of it with "Who shot Mr. Burns?", only exist because of how shocking the idea of a cliffhanger was at the time.
Now, every season of every show ends with someone getting shot, or killed, or kidnapped, or quitting the force, or whatever... and they've become so meaningless that none of them are really cultural events that will last into the next generation.
Like, I can't really think of a single cliffhanger finale for
Lost. I mean, "WE HAVE TO GO BACK" is probably the only one that immediately comes to mind but I don't even remember the context of that ending.
I watched 5 or 6 seasons of
24, the show defined by the cliffhanger ending, and I can't remember any of them. I think in one season Jack goes to Africa to save some orphans and he gets captured and returned to the US or something? Who knows.
I don't know if there's a solution to that. David Simon's pseudo-cliffhangery-but-not-really endings to his seasons are pretty good. But then again, no one likes his shows so that's probably not the best way to go about it. lol
I'm consuming a hell of a lot of fiction at any one time so that might have something to do with my personal recall. With Lagrange specifically, I think the fact that so much of the first season was just setup--a piling of mysteries upon mysteries and context-less terminology--harmed my ability to remember a lot of it. Knowing the underlying reason why a character is doing something or why a fictional world works the way it does improves my recall.
Alternately, maybe I just didn't give a damn about the srsbns in the show to begin with and really just cared about the cute girls, hahah. I do also have to be invested in a narrative to retain it for a long time beyond the point of consumption.
Not enough Miracle Trains, clearly!
