Generations for Federation
Keep First Contact, but if that had to change, I'd go with Vendetta
Insurrection for Q-Squared
Don't know what I'd switch Nemesis for, but something a lot more satisfying of a conclusion then what we got
My God, you invaded my mind! You must be a Betazoid!
Seriously though, absolutely agreed on GEN and INS's change. Though, Q-Squared would have to be heavily realiant on the show, so maybe do a new plot...
How about bringing in those parasites from TNG's season 1? You know, from "Conspiracy" and all?
The plot could've been, these parasites were the ones to have invited the Borg in "Conspiracy"'s finale. They wanted the Borg to assimilate all worlds, except for the Trill society, which they wanted to subvert and conquer for their own. However, with the Borg's failure in FC, they seek, and find, new alliances in a new species, which forces Ent-E to deal with, while conviniently the Dominion War is happening (thus, explaining the ship's absence then). Also, no Worf as a consequence.
So, ideally, I'd have:
Federation
Shatner's
The Return
First Contact (filmed before The Return, whose popularity would have forced it to be adapted, as a FC prequel)
The Parasites proposal, a direct follow-up on FC
Nemesis, though HIGHLY polished, and perhaps Spock-inclusive.
What do you think?
