The problem with this analysis is that it assume everyone has the same tastes, and stuff you don't personally like is "garbage." The reality is that people have a lot of different tastes. I don't think you should judge Netflix by what you don't like; only by whether it has enough of the things that you do like.
For example, I've been enjoying "Handsome Siblings," a Chinese wuxia show that's pretty shallow. It's not going to win any awards for writing or acting, but it's beautifully produced and good mindless fun.
To some people, it's filler junk (worse—subtitled junk). To me, it's perfect for passing the time on a long plane ride.
Yes, I didn't like any of the shows the person you are replying to listed. Although Netflix still doesn't have any shows I like, I've only been enjoying Apple+/Hulu, hell even Amazon.
The series that are really well made are few and far between. E.g. - Narcos - Ozark - House of Cards - Stranger Things
For every good show, I see another few dozen that I can't bear to sit through. Stuffing the catalogue with filler is reminiscent of cable.
