Series produced by streaming services just can’t seem to write self-contained seasons without leaving unresolved plot lines as a hook to keep you subscribed, but they’re also just ruthless in acing anything once the numbers dip a touch. It’s gotten to the point where I see “Netflix original” or whatever as a massive red flag when picking something to watch, as I know there’s a high chance I’ll never get any resolution to the series.

The scenario you described has basically taught me to wait a season or two before I binge-watch anything on Netflix, to make sure a series never ends on a cliffhanger that won’t be resolved.
