Mad Men didn't even have an audience when it aired (<2 million viewers most episodes), and airs on a network that likely won't exist in 5-6 years (or at least won't be producing new content), so it's not super clear to me what your point is about those shows as evidence of how a network grows. The way a network grows is by producing content people want to watch, whether that's disposable content made to last a minute or content made to last the test of time. HBO isn't growing because people are subscribing to watch Sopranos re-runs.

Past reporting suggests churn in most subscription content services is very low, so your Netflix cancellation may be unusual. I'd also add that exclusive content is one part of the story, but there's also a lot of licensed content that's very good on Netflix as on other services.

But for what it is worth, I would rank the following Netflix originals to be "top tier" within their genre -- some of these genres lend themselves more to rewatching than others, and some are closer to my taste than others, some held up in quality through their run more than others, so in a sense I am ranking shows based on their peak quality --

Orange is the New Black; Bloodline; Stranger Things; The Crown; Gilmore Girls AYITL; The OA; A Series of Unfortunate Events; Mindhunter; The Haunting of Hill House; Unbreakable Kimmy Schmidt; Master of None; Love; Lady Dynamite; Santa Clarita Diet; GLOW; American Vandal; Maniac; Bojack Horseman; F is for Family; Disenchantment; Hilda; Dark; The Rain; Elite; Chef's Table; Making a Murderer; Shot in the Dark; Wormwood; Wild Wild Country; Salt Fat Acid Heat; Queer Eye; The Curious Creations of Christine McConnell; My Next Guest Needs No Introduction; Lilyhammer; Terrace House; Alias Grace; The End of the Fucking World; Collateral; Wanderlust; Longmire; Black Mirror; Comedians in Cars Getting Coffee.

In addition to these, the following shows are Netflix originals in my region, indicating that although someone else initially funded them, Netflix bought them for exclusive distribution here, and also meet the above requirements:

Babylon Berlin; Bodyguard; Casé; Crashing; Cuckoo; Derry Girls; The Great British Baking Show; Happy!; Happy Valley; The Investigator; Peaky Blinders; River.

I have pretty broad taste in TV and watch a lot of TV while I am programming or running data analysis, so maybe the breadth of stuff I include here is surprising to most. But to the extent your post is a useful anecdote about how Netflix has no great shows, I'm responding to your challenge to "Name one show" that would meet that criteria.

(These are TV shows only, not films. I haven't really liked many Netflix original films although there are a few I would say are great, like Okja and Roma)

Of all the shows you mentioned the only ones I have watched is, OITB (left it at after watching S04 I think), Master of None (both the seasons), I realise that its a drama that leans toward being a rom-com but I do not watch rom-coms at all. Kudos to Mindhunter, indeed that was entertaining and right in my ballpark. Liked House of cards till the time Spacey was there, S06 disappointed me. Season 1 of Making a Murderer was outstanding, season 2 didn't catch my interest. Also the last comedy I watched end-to-end I think was Entourage (which was produced by HBO), The Office (US) and Parks And Recreation, not surprisingly Netflix doesn't stream any of these in my region, Prime Video does the last two and Hotstar streams Entourage.

These are good shows not great ones like The Wire, The Sopranos, Mad Men, BB, Six Feet Under you know about the stuff that critics rave about etc. I don't care if Birdbox was watched by all of Netflix's subscribers, thats precisely the sort of thing that I don't watch the majority of the time, you watch that thing once and you forget that you ever watched it again. I'm now on probably my sixth or seventh rewatch of The Wire, that should tell you something about my viewing habits and why Netflix's content just doesn't work for me. I don't expect a network to consistenly churn out shows like that but at least some of the shows should be somewhere close to that level which HBO continues to do with The Deuce, Succession, True Detective(I know they fucked the dog on S02) etc.

Also you have the time to watch ALL of that, I don't. I work in tech too, I have an hour on weekdays and maybe 2-3 on weekends for leisure, so its only natural that I would be picky about what I watch, the absolute best, currently that would mean shows like The Americans, Escape from Dannemora and shows from the past like Halt and Catch Fire(from AMC), Six feet under, Deadwood which not surpisingly were also made by HBO. Netflix doesn't stream any of that.

I also don't understand how you think AMC won't exist, are they going to be insolvent ? Doesn't look like it, they have a cash-cow in The Walking Dead(I only watched till S06 then got bored) They got two of the best TV shows I liked BB and BCS, BCS is gonna kill it in the next season. They also produced The Terror, a brilliant mini-series which Netflix didn't stream as well and again Prime Video did. As a viewer I don't care about Netflix's subscriber numbers or HBO's lack thereof, I want to watch content I like which sadly Netflix doesn't produce on a consistent basis, this is entirely subjective and I realise that I might be one of the edge-cases in all the millenials when I say Netflix don't tickly my fancy.

I'm not biased towards HBO, hell HBO doesn't even stream in my country, I'm incredibly picky about what I watch since I'm short on time, Netflix churns out a LOT of shows, its only natural that some of them turn out to be brilliant and some of them indeed are, but the rest, like 90% of the shows are just average, they don't work for me, I simply do not have the time to watch them.

In that sense, Netflix is like the Y-Combinator of producing original content. You produce(invest in) hundreds of TV shows(startups) and hope one of them makes it big (becomes a unicorn) and the rest of them, well they would be probably cease to exist after some time.
