They're certainly not hurting for content. I swear 50-60% of the thumbnails have the Netflix N logo on them. They have too much content, spending too much money on content.
They could easily tighten up their spend rate and still have a shitload of content. They certainly need to be more focused.
Their issues are ironically solely content-related, if the (good) content is there, people will be willing to pay for it, account sharing or not.
The problem is that there are a lot of great unique shows and movies, but that content is overshadowed by a lot of mediocre filler stuff or forced woke agenda injection, that's two topics people seem only to talk about regarding Netflix despite amazing unique content it provides, for example Love, Death + Robots is getting 3rd volume next month and I simply cannot wait for it, that's exactly why I'm subscribed, same for Arcane S2 which won't arrive in 2023 at earliest. But this kind of high-quality content takes time, 1-2 years to be precise, while the gaps are filled with stuff like recent Windfall...
So what Netflix should IMO do is, as always, focus on quality instead of quantity, not even cut their spendings, but spend the same money on lesser but better stuff, so instead of having a new premiere of just something, anything every 2-3 days there's just a handful of but really high caliber movies/shows.
The other issue is also that whenever something is indeed good and successful they often milk it rather than just have 8-12 episodes of a complete, closed story and move on, for example 'Who Killed Sara?' was awesome and didn't need any sequel at all, the cliffhanger was completely unnecessary, and literally few day ago I saw a trailer for 3rd season, why? And supposedly she's not even dead at all, that's how much they twisted the plot just for the sake of milking the franchise. Altered Carbon, same deal, it was a complete story, the mystery has been solved, case closed, and yet they decided to make a sequel which honestly didn't have anything to do with the first season, you just cannot replace entire cast like that and think people will like it. Thete are a lot more examples obviously, while that time and money could've been spend elsewhere, on something new but equally good.
