I guess I'm Gen X. Or a very young Boomer. I've just stopped watching TV altogether. "News" is a joke, and everything else seems like a waste of time.
Fiction writers love to play this trick with book trilogies and book series. So I don’t start a book series unless all books are already in print.
It's obviously fine to prefer some and not others.
You can equally see TV seasons as giving the opportunity to take a break from something for a while.
I also don't like the season-after-season thing you're referring to, but I am encouraged that over the last 3 or 4 years we've seen a small increase in the number of stories being told with a defined story arc, and no sequels.
