I wouldn't mind that as much if it was a) an actual movie, and b) NOT CALLED THE THIRD SEASON OF A TOTALLY DIFFERENT SHOW!
First off, aping the TOS movies isn't a great story idea, but whatever. Unoriginality is the least of our concerns. The real problem is that this isn't "Star Trek XI: The Wrath of Borg" or whatever. It's season three of Star Trek: Picard, a show we only got one season of. Season two was two things: an excuse to build sets for three, and a way to remove everything that made season one good from the playing field. Season one established a world in which the Federation had retreated inwards, and Picard with it. But he built a new crew on a new ship for one last adventure and went back out there, the season ending with him and the La Sirena flying off into the space-sunset.
Then season two comes along and yells "Wrong!" Rios gave his beloved La Sirena to Seven and became a Starfleet captain, Soji went on a bus to elsewhere and was never mentioned again, Picard rejoined Starfleet offscreen -which he swore to never do- and so on. Then they went back in time and left behind everyone except Raffi, Seven, and JL himself.
Season three had nothing to do with either of these seasons, and was your "last TNG 'movie'" despite having no right to do so, as it wasn't a TNG movie, it was a Picard season. And Picard, despite the name, was about more than just the man. But they killed all that to do one last hurrah to something Picard had originally avoided for good reason.
