Problem is they’d cancel a lot of stuff that did stick. Ending so many shows after one or two seasons and letting them end unresolved leaves a bitter taste in a viewers mouth. I quit watching almost any Netflix show before knowing the show has a proper ending. I’m sure they’ve put off the final season of stranger things over the last three years less because it wasn’t able to be finished sooner and more because they think a bunch of people are still subscribed only because they’re waiting to see the finale before unsubscribing.
