Early-Disco is the only Pre-TOS thing I'm a fan of, specifically because it was so different that it made me forget about it. As far as the Klingons, I've already said everything I wanted to about them back in 2017-2019. As soon as Picard was announced, I knew they'd work their way back to TNG Klingons because I thought if Worf were to ever appear, there was no way they'd make him look like a Disco Klingon and Michael Dorn wouldn't have agreed to it anyway.
My final thoughts about what I would've wanted for Section 31:
If you look at "Inquisition" and "Inter Arma Enim Silent Leges", something in that style is what I wanted. Keep Georgiou, keep Alok, keep Garrett, and keep Quasi, but drop everyone else. Go more into these specific characters. Show more of their backstory and motivations.
Sum up the situation in the 2320s. The Romulans are out of the picture, the Klingons are still recovering, the Cardassians are on their radar but not a problem yet, have all this in a briefing where they talk about the status quo (and bring the audience up to speed), then shift the focus to what else is going on in the galaxy. Then they're acknowledging, "We can't do anything with the major AQ powers because they're locked into their status quo until TNG, but we can do something with these other races that we don't know anything about!"
So that's the tone I want, the greater emphasis on the characters, and we have the framing of the Lost Era and it looks like a deliberate choice instead of a random one.
Also show that Section 31 and Starfleet are two different sides of the Federation Coin. And address head-on the biggest debate in Star Trek: "Humanity has evolved" vs. "Human nature will never change". Throw in "We have to do what we do so you can do what you do."
All of that would've summed up Section 31. This movie didn't go into any of that. They purposely went out of their way to avoid all of it. What I wanted was a movie that has its own specific viewpoint even if someone doesn't agree with it. This movie gave all that up just to be popcorn entertainment that can't measure up to other popcorn entertainment.
Fin.
