My big problem with the 32nd century was always that it wasn't different enough from the "standard" ST universe to justify it being set 8 centuries in the future.
Before Paramount decided to go with the J.J. Abrams' films, there was a pitch from Bryan Singer's production company for a series that would have been named
Star Trek: Federation, which has a lot of similarities to
Discovery post-season 2.
It would have been set in the 31st century and featured a Federation in decline with only 20 member states left. The action would have been centered on the newest version of the Enterprise, the first starship to carry the name in centuries. Klingon society has evolved into a sort of Zen Buddhist warrior ethos which has mixed spirituality with their views of honor in battle. The Ferengi have become a major power through economic manipulations. Similar to the Bajorans, Cardassian society has returned to its spiritual roots, and the Ferengi have monetized "pilgrimages" to the Bajoran wormhole as a religious event. At least in the initial running, a new threat called the "Scourge" would have been the "big-bad."
The biggest difference between the proposed
Federation series and what we got with
Discovery is there would have been no outside event like "The Burn" responsible for the Federation's collapse. Instead, the Federation has devolved into apathy and resentments from member worlds who felt policy was too human-centric. Part of the backstory for the concept was human society had become complacent and arrogantly believed in the superiority of their way of life. Instead of exploring outward to learn more about the universe, humanity turned inward.
Another issue I had with SFA + The Burn era is it made the same mistake of ENT. It tried to combine two interesting ideas and neither one was able to meet its full potential because it was too much. ENT tried to do the rise of the UFP + Temporal Cold War. Each one is enough for its own series and should not have been merged.
Another similarity to ENT is just natural burnout.
By the time of
Enterprise, it was the 4th series of the Berman era, after
Star Trek being on TV for more than a decade all the way back to the start of TNG.
SFA is for all intents and purposes a spin-off/continuation of the later seasons of
Discovery. It exists in
Discovery's setting, it has characters from
Discovery, and it uses the aesthetics and tone from
Discovery. And
Starfleet Academy is the 8th property of the Paramount+ shows after almost a decade.
For any long-running franchise, whether it be
Grey's Anatomy or
NCIS, the longer things go on and the more shows you try to spin off from it (especially when the spin-offs are meant for specific niches), the brand becomes more diluted and the audience falls off.
