Seems like 'Watercooler cooler' tv peaked with GoT and every other attempt (WestWorld, Rings of Power, Succession, etc) has generated some buzz but nothing near peak GOT S3-S4.
And now that it turns out there's no lasting economy of scale with subscription tv (wait for full season to drop, subscribe for a month to watch, cancel), I doubt there will be many more big-budget shows in the future, at least until business models change again. Apple, Amazon, and Netflix (to a lesser degree) subsidize their shows but I feel that's going to be ending in the next few years.
