Yeah. But I wish we would get some new original franchises. Almost all the ones milked right now are 30-60 years old.
We won't get many large franchises again. Nobody is producing 100 episode series with the same cast except for cheap fantasy procedurals (fantasy from the scripts, set in the current day), let alone multiple ones.
"The Expanse" ran to 62 episodes (and itself was based on a book series). Game of Thrones 73.
For All Mankind has a spinoff, but 40 episodes in 6 years and maybe reach 100 episodes over 10 years and two shows, although I'm not convinced as they progress further into the future.
There have been some long lasting TV series (say over 65 episodes -- so TOS numbers) that have been airing in the last 20 years, mostly set in modern day though, and almost all in the broadcast era. Supernatural and Walking Dead come to mind, but also
* Once Upon a Time (well characters were based on fairy tale characters so maybe not genuinely new)
* Fringe
* Warehouse 13
* Eureaka
And ones based on previous works (Agents of Shield, the DC Arrowverse, Smallville)
But to get to original franchises in my view needs a lot of episodes and needs to deliver them quickly to keep the interest. 10 episodes every couple of years (Apple's production schedule) doesn't really do it.
