I'm relatively new to binge-watching via streaming. With DVD's, you knew where it was in the season and which season by when you had to change the disk, but I've been letting them go from beginning to end.
So not only was I not prepared for the end of Season 3 of The Marvelous Mrs. Maisel, I thought there was a blip when the next episode didn't come on, and went to the drop-down box. When I clicked "Season 4," it told me to come back in February 2022
The end of Season 3 was predictable from about the first minute, but it's such a shame that story arc ended (for reasons I can't figure out how to explain without spoiling.)
