One thing I hate is that Star Trek doesn't explore that period between TOS and TNG, it seems like it would be interesting. Like with a lot of the technology of TNG, but some of the mystery and federation expansionism of TOS.
When I think about going past Voyager and DS9, I tend to find that it's something that sounds better on paper than it would pan out in reality. There's still a lot of the universe to explore, and there could be a new galactic frontiers to develop. But it seems like technology will be good enough soon to zip into the Delta and Gamma quadrant. Another potential is to make it about some new powerful Galactic Core Empires that even the Borg would be afraid to approach. Or do what Stargate did and find a passage to a new Galaxy.
I describe myself as a little dose of toxic masculinity.
