It really can't. I stopped watching The Next Generation and followed Deep Space Nine fine.
I stopped watching
Voyager but I can't deny that it left elements that you just can't ignore, since they've been used in other shows (e.g., Seven of Nine, the effects of Janeway's actions against the Borg, etc.).
Prodigy uses many elements of
Voyager as a basis of its backstory. You can watch it without knowing about Janeway or Chakotay, but it does add depth if you understand
why Janeway is so passionate about finding Chakotay.
All of the series have elements that inform the rest of
Star Trek and affect the fictional history the other series have to work around. The Battle of Wolf 359 from TNG is a major event that colors a lot of the Berman era, including
Deep Space Nine especially with the characterization of Sisko from where he starts the show to where he ends up. Aspects of DS9's Dominion War have had long-lasting effects that have permeated throughout almost every other Trek series since it (e.g., Section 31 has been used in almost every
Trek property, both film and TV, since DS9).
And I'm guessing that some of the choices from
Discovery are going to be the basis for
Starfleet Academy if as expected it's set in the 32nd century. Fans being vocal about the choices they like or don't like may be inconsequential, or might make some of those in charge rethink things. The absolute awful reaction to the season 1 Klingons probably meant we didn't have to live with the disastrous redesign of the Klingons in every other Paramount+ series since
Discovery.
I just have this weird thing of people watching things they (check notes) actually like, rather than constantly courting disappointment. Yes, I'm strange. I stop watching things I'm disappointed in.
I like
Star Trek. This is still
Star Trek. It's the only new
Star Trek thing on right now and it's coming to an end. So I want to give it the benefit of the doubt even if I've been disappointed in the past because it is offering new stories (and background) to the
Star Trek universe. But I'm still going to say I think it was meh if it's meh.
There was no reason for Starfleet Headquarters to sit around waiting for the Breen Dreadnaught to show up instead of just Warping away. Instead they just didn't warp away, because the writers said they didn't warp away.
One part of the worldbuilding that annoys me, especially after season 3, is we're not really given a sense of what exactly is the state of the Federation in the time since they began recovering.
We know some of the former members have come home. And given the response to the DMA, it seemed like it had started putting the pieces back together in season 4, given the cooperation in deciding how to proceed.
But Starfleet HQ and a handful of ships surrounding it always seems to be the extent of the fleet. The fact that ONE Breen Dreadnought is enough to threaten the heart of the Federation, to the point they have to use 800 year old tricks to
seem more powerful on sensors, just seems off.
I mean if this
one Breen ship is enough to be a threat to the Federation capital, I would not feel protected by membership in the Federation and think there is something seriously wrong with its defense policy.
