No one will agree on what is the best way moving forward. I generally like the Kelvin Films, but I am a Classic Trekkie. But, we need to bring all these elements forward, so, with spoiler:
- Acknowledge the shenanigan known as the Temporal Cold War, hot and cold, and how that has affected the 'Trek Timeline.
- Include key players, from different eras (TOS, TNG, DS9, VOY, KELV, DSC, etc.) be aware of what is happening, and why they are assembled to "fix" the situation (it's doesn't have to be everyone, just the key people needed to get the job done); maybe all the "captains" get assembled, in some way or another (probably not, due to the expense)?
- Start with a mini-series on the streaming service as the "preamble", but resolve the crisis in the movie, featuring the Kelvin timeline crew.
- Have some reveal as to who was responsible for the crisis (i.e. too many paradoxes is destroying the fabric of reality, blah, blah, blah), but with a twist; no REVENGE (Chekov was behind it all??? LOL
).
- Crisis is resolved; Q (John DeLancie) appears, congratulates our heroes, and, with a snap of the fingers, reality is reset; we also get to find out who is the mysterious Koala.
- Timeline resets to its "proper" flow, however it pans out, with "updated" aesthetics (in fact, I wouldn't mind pushing back key events within the STAR TREK universe a hundred years or more, just to keep "The Future" a bit more distant).
- We move forward with a "new" crew, whether it's new, younger actors playing existing roles, or simply start fresh with a new cast.
