During the last season of Voyager, my strongest memory was thinking about how many missed opportunities they had. I think a lot of people felt the same way, so this thread is your opportunity to rewrite the events leading up to the ending.
1. Full circle ending just like TNG and DS9. Voyager finds the home of the Caretaker species and there is a massive battle between the 'sporocystian' lifeforms and the borg, which results in them sending Voyager home, and the caretakers going to war with the Borg to protect the galaxy just as the original Caretaker protected the Ocampa.
2. Borg origin story. Voyager abused the hell out of time travel, having like four episodes per season, and it never occurred to them to go back in time to the Borg homeworld, right before they became the Borg? They could have massive ethical debates about the 'Temporal prime directive' when they could save trillions of lives but completely rewrite the timeline of the entire galaxy in the process.
3. A couple episodes after getting home. Why did they not get to Earth until the final scene? They had a brilliant opportunity to show them trying to re-assimilate, to see them have to deal with the Maquis division they hadn't thought about in years. The Maquis would obviously all be pardoned, but accepted into Starfleet at their Voyager field rank? And would they want to stay in Starfleet or go back to try to rebuild their colonies that had been destroyed by the dominion? And what happens when Janeway meets Mark again? So many missed opportunities.
Basically I would have had them get home a with five or six episodes left, then in the last episode, some ship on the edge of Federation space meets a caretaker and Janeway gets called in due to her experience with them.
How would you have ended the show differently?
