Sorry, that's like suggesting there is a best way of writing a series of novels, as if they are just one bigger novel. Which is emphatically not true.
I don't think the analogy holds however, because novel series are generally constructed in one of two ways.
One is, of course, construction as one big epic novel, in which case (unless you are George R.R. Martin or something) the books tend to come out in a roughly clockwork fashion every 1-3 years, because you don't want the reader to lose interest in your series.
The other common method is when authors first write a largely self-contained story but later decide to expand it. Good SFnal examples are Ringworld, 2001, The Forever War, The Mote in God's Eye, Gateway, A Fire Upon The Deep, etc. Often the gaps between these can be much longer - over a decade - because each book is telling a new story within the wider universe with some of the same characters, not a continuation of the old story. It also gives the author plenty of time to mull over what a new arc will look like and ensure the sequel will not be a total flop.
Honestly, the book analogy of the Discovery format - where each story is largely self-contained besides the characters, and each one builds to similar epic stakes. Honestly The Expanse novels are probably the closest, in that each has a unique antagonist who is defeated by the end. It works though, because the individual books are all written with nods to different genres (noir, western, spy thriller, ghost story, etc) meaning tonally the books are quite different. Still, they are basically pulphouse level stuff, like Peter Hamilton or Kevin J Anderson. I feel like Star Trek should aim higher than that.
I can be quite frustrating for a reader/viewer's who's followed along for years and then finds their show is gradually going in a direction they don't care for because of the 'big plan' and have grit their teeth at the unwanted "payoff".
The exact same holds true for shows which have season-long arcs. By that rationale it's best to go back to episodic, since surely some of the episodes will be to your liking.
QUOTE="ITDUDE, post: 12918284, member: 490"]Starfleet Academy - no hero ships, no epic battles, no saving the universe. Just regular every day life (in a Star Trek setting). Lots and lots of people here have wanted this show for last 20 years.
Worf Chronicles - adventures of everyone's favorite Klingon. Lots of battles and "today IS a good day to die" pew pew pew stuff, but certainly he wouldn't be saving the universe every season.
Section 31 - Spy thriller, assassinations, rogue agents, cover ups, Federation's dark side (not for everyone, but could work)
All those do NOT have to be saving the universe from a new Big Bad every single year.[/QUOTE]
My own idea for a Star Trek show is to follow a young Curzon Dax when he gets stationed as a junior diplomat on Qonos. We could see him slowly build up his friendship with Kor, Koloth, and Kang, eventually being instrumental in the Khitomer accords. Plus he's the sort of flawed but likable character (roguish, a bit of a drunk, lecherous towards women, and maybe men if we retcon Trill into being pan) that I think would go over well in the modern era.
