I dunno, HoC went off the boil before. And it wouldn't be hard to write a better last season

Agreed. I loved seasons 1&2 of stranger things but I was over it less than halfway through the third season. But they had a low budget high school zombie show that was enjoyable but they ended it immediately. Like, I don't know what their issue is, but the fact that they don't understand their audience is clear. The fact that they're still around is owed to the fact that they were first to market, and now have lots of content. But most of the good stuff is just rented by Netflix from other companies.

Mindhunter was also great, but rather than losing their audience with huge gaps, they lost their showrunner and cast.

House of cards and mindhunter came from Netflix trying to give money to people that knew how to make quality shows and not interfering. Then they decided a different strategy of trying to appeal to lots of different demographics with low quality shlock. It destroyed the quality of everything. Now Netflix original means terrible, like direct to video was in the past.
