I'd be shocked if we don't see several (if not all) Next Gen cast members announced as signing on in major roles in the coming months. Given the critical and financial success of other recent revival miniseries events/belated series finales (Gilmore Girls: A Year in the Life, 24: Live Another Day, Twin Peaks: The Return) I'd imagine Kirsten motherfucking Beyer and Patrick Stewart are thinking "Well, Next Gen ended with the wet fart that was Nemesis. Let's do this properly".
The TNG crew got a proper send off in Nemesis. The crew had one last adventure together, then they all moved on. The story wasn't any less shitty than Star Trek 6 (yes, that movie sucked too), it's just that the general audience didn't care about the TNG crew like they did the original. And that's saying something considering that TNG was a much, much bigger hit in first run. And THAT is the real pisser behind all this "proper send off" noise that we've been hearing for twenty years now. That despite greater popularity in first run, despite breaking records in syndication, despite critical acclaim, general audiences didn't really care about them going away. Both Nemesis and Star Trek 6 were mostly shit with a few good moments in them. Both films had good endings, the only difference being that Star Trek 6 ended with the crew sailing into the sunset and into legend. Kirk and crew were mythical, and we could imagine them sailing the stars forever and having endless adventures.
The TNG crew was never legendary in that kind of way. The TNG crew was the more down to Earth crew, the one that moved on from the Enterprise, that went on to other things and chapters in their lives and more believably so. And the end of Nemesis reflected that. Life went on like life does. One friend died. Others went their own way to be replaced by new crew mates who in time would become old friends to those who stayed behind on the Enterprise. So no, they didn't get their "sailing into the sunset and myth" moment, but they had the more believable ending and it was just fine.
And god I hope this Picard show is just that. Aside from him, Burton and Spiner, I've never been too impressed with the rest of the actors, I liked them enough back in the day, but have zero interest in seeing them now. Based on Stewarts words, this doesn't appear to be a nostalgic reunion show and thank god for that. He said that it would be about Picard in the next chapter of his life and would deal with his experiences leading up to that. He's not still sailing with the Enterprise crew, and those folks are the people he used to work with at a job he had twenty years ago. Between now and then, he's met scads of new people, made new friends, maybe married, who knows. I'm more interested in seeing Picard as a regular person in a more grounded setting. Not on a ship, or station. Not part of Starfleet. Just an elder statesman who maybe does some teaching, or some archaeology, or working on his memoirs, in the later days of his life.
We need fresh new windows into this world, and we've already got a "traditional" Trek for 2018 in DSC. I'm not interested in seeing yet another crew on another spaceship, or a lame ass "fall of the Federation" thing. So hopefully this series or mini-series (whatever it is) will give us a fresh insight into the world of the Federation.
