Here is Amazon problem in two sentence.
You can't buy taste.
You can't force art.
They are giving way to much money to people with no track record. It is insane when you look at the CV of people involved in some of these shows.

They have never directed anything before, let alone been showrunners of anything.
What kind of executive sign these checks, FFS.
They were in a race and getting virtually free VC and gov money. The upper limit of streaming revenue is almost limitless, 8 BILLION people at $10-15/mo, so what's a few billion burned now? These guys just needed to stay ahead of ballooning interest payments.
But that balloon is full, possibly contracting, now, so the debts have come due. The talent has been stretched too thin, "they" shouldered aside solid, reliable performers in search of "new voices", started running everything through algorithms to make sure SOMETHING in EVERY show appealed to EVERYONE, but forgot that those fringe groups, while in aggregate a decent size, are just fractional splinters and not at all harmonious with each other. So they are shedding a majority audience in pursuit of 1% groups.
With the writers strike stopping all US based stuff, I think we will see a massive bidding war for asian content but even the most lavish production is a tiny cost of a Citadel or Rings of Power. They will be able to mine that stuff for a few years until the novelty wears off and hopefully by then we are back to properly balanced domestic shows.
