Rewriting history is hard. It's especially hard when rewriting history that no one wanted to be rewritten. That's an issue we have in everyday life with how some people like to retell the events of a situation but incorrectly. Sometimes to make one side look nobler than another. It's also an issue in science fiction, where people will try to retell history just to make their stories fit better.
When it's done in sci-fi or fiction in general, it's usually to try and copy the success of things that came before it and to further explore the era in which the story is set. The problem with that is that often the writers will steal elements of the era they want to set their stories in while throwing out everything else that they don't like.
It's not exactly a good idea to do on its own, let alone in a franchise as rich and deep as Star Trek. Star Trek: Discovery did this exact thing. They created a show that on its own would've been fine but the writers wanted to add more unnecessary emphasis to the story by saddling Spock with an apparent adopted sister he never had before.
It was an idea that was poorly received and altered too much of the period for fans to accept it. This, among other issues (like Discovery as a whole creating a new warp technology that no one ever bothered to save the information on), led the show to be panned for years to come. Knowing this, it's a bit surprising that Star Trek: Section 31 would opt to follow in the same
Section 31 is being set sometime after season two of Discovery and will feature Michelle Yeoh leading a new version of the clandestine spy agency. Yet, this version of the secretive-torture-unit is still very well known to many in the federation. This is a problem, as season two of Discovery did all they could to set up the spy agency that we'd come to find during the events of Deep Space Nine.
The trailer seems to suggest that the ideas and intent that Discovery season two set up will be thrown out the window for the new made-for-streaming film. If that's the case, then this will be yet another origin story for a unit most known for its torturing of Federation officers.
An origin story no one was asking for. It's just more of the same with this group of Star Trek producers, who want to muck around in past concepts that are superior to anything they're doing and steal aspects they want while throwing out what they don't.
Section 31 likely continues to tear open holes in the long-running plot of Star Trek and if they do that, there's no chance this film will succeed.
