I was reasonably entertained while watching the movie, but ultimately I can't quite figure out what the show was trying to say.

Given that "Section 31" was originally conceived as a series, I think the influences of that are clear. For example, the introduction of a band of misfits that are clearly meant to keep on adverturing and the framing device of "transmissions" with individual titles.

The challenge is that the time we were allowed didn't give us enough time to really know any of the new characters, which is a shame because they offered an interesting and rare opportunity to see what life is like in the ST universe outside of Starfleet. Those unique perspectives are one reason why DS9 continues to be so well-regarded and why I found season 1 of PIC actually quite compelling.

I think the shorter format would have been better served if it was a story exclusively about Georgiou finding a new place for herself after what she had learned from her DIS experiences, maybe leading up to a final confrontation with San which interrogated the idea of a "good dictator". Indeed, I found the flashbacks and her interactions with San the most engaging parts of the movie. But because that comprised only a small part of the movie, we didn't really learn much more about her than we already knew. And the actual bond/conflict between them was never particularly clear, with San's motivations coming from left field.

The movie also suffered from what I call the "Inception effect" which is that it set up some potentially interesting mysteries but then solved them in the most boring manner. Having Fuzz be the mole was such an obvious choice, given that they had clearly established his ability to control electronics. As I was watching, I actually thought he was a red herring and that Melle was the mole all along, using her masked accomplice to fake her death at the beginning (a la "Gambit"). That would have at least turned Melle into an actual character, but I guess Deltans are cursed to die in the first third of any movie they're in.
