I'm surprised how many comments there are to the effect of "you can't have a multi-season 'Year One' series!"
Of course you could. The writers choose how fast time passes in-universe, and (unless your cast includes children), time in real life and on the show do not have to be synced. It's common for there to be TV shows where the whole season occurs in a compressed window of time.
For a recent Trek example, Lower Decks covered about 2 years of in-universe time during its five seasons.
"True Blood" and "Lost" also jump out to me as shows that particularly manipulated their timelines to be whatever their story needed.
Yeah, I'd rather have a TMP-era Year Six than Year One. Get some of that generation-Matalas movie-era nostalgia pumping, plus it's more open-ended.
On the other hand, they've done a surprisingly good job of recontextualizing TOS already; like I always say, if someone dumped me in a splashy song-and-dance number then decided they wanted to get back together, I'd throw their soup in the hallway, too.
This sums up my feelings exactly (including on Spock/Chapel, I'm regularly stunned how well their modern SNW story tracks into TOS). Though it's possible to do multiple seasons set within one calendar year, it's a much better idea to go post-TMP.
But honestly, I don't think any form of a Kirk-centered series could be satisfying, because Paul Wesley is the only serious casting misstep of the modern era. He's horrible in the role, and the only thing no series can overcome is a bad lead.
We're just in the first phase, where TPTB try to get fans worked up into making it happen.
They haven't even finished making the show that got cancelled yet, and we viewers are still two seasons from it being over. Any bump in interest right now would be pointless, in my completely unprofessional opinion.
In my recently-retired-from-entertainment opinion, there's no better time.
I mean, I'm skeptical of the impact of this approach, but they're timing it to the merger. Decision-making at Paramount has been stalled until that resolves, and now the new bosses are going to start making big-picture decisions on how all the brands will be managed going forward. If there's going to be a next show, the time to start developing it is now.
Though I really hate this "we have the sets!" pitch, because for me it highlights a big financial problem with this idea, which is that most of the core cast is already expensive.
The reason you cancel a successful existing show, to start a new show on the same sets, is to cut all the people whose salaries have grown large over years of annual bumps, and start again with a new team at low first-season rates. But in this case, we'd have to carry over an already-expensive Kirk, Spock, Uhura, and Scotty (and maybe Chapel and/or M'Benga?). It makes it a much less appealing proposition, money-wise.
