To an extent yes. There has been some utter crap. Another Life pops immediately to mind as something so unwatchably terrible that i watched just to see if it could get worse (spoiler: yes! wow... so much yes!)
But that isn't a netflix issue, that's just an issue. From Firefly to The Expanse to Babylon 5 sci-fi especially is hamstrung by its production.
But there's been plenty of good shows to watch too:
I quite liked Fall of the House of Usher recently for example.
Black Mirror, Maniac, Umbrella Academy were good.
I watched the The OA Season 1 and that was good (I skipped part 2 since i knew it was cancelled mid-arc.) Dirk Gently's Holistic Detective Agency was brilliant - especially season 1.
"So, books have always been more my thing. I'm sticking with them."
Sure, I like books too.. but Game of Throne's is a mess that may never be finished and perhaps shouldn't be; and Wheel of Time never was. And even Asimov's foundation is actually better without books 4 and 5, nevermind the Benford books, and Dune ... likewise did not improve with more novels, and also fell off a cliff when other authors kept it going like a zombie corpse. Things that are 'good' always invite 'more' and the 'more' is almost never as good.
These days my favorite books to read are those that are not part of a series, or at most are a trilogy, and have a beginning middle and an end and above all: a point. They don't try to milk the setting or characters endlessly. With each successive book in the series getting longer and longer as less and less editorial control is exercised over an author seemingly paid by the word.
