You know, I don't have a problem with Star Trek: Seven of Nine. I don't particularly have a problem with Star Trek: Enterprise-G. But the whole idea of Star Trek: Legacy -- which suggests a show that is backwards-looking, mired in permanent nostalgia, gives its budget and creative energy to old characters instead of new, and is generally fixated on the past instead of looking forwards to the future... that seems genuinely antithetical to the spirit of Star Trek at a certain point.
Like, there is a reason Gene Roddenberry created Star Trek: The Next Generation instead of Star Trek: What is Captain Kirk Up to These Days.
That juxtaposition, in fact, between the two titles -- The Next Generation vs. Legacy -- says a lot about the difference between their creative visions.
I think you're putting WAY too much stock into something that's just a name. You've built it up too much. Supposedly he wanted PIC S3 to be called "Legacy". Which, there, makes sense. But he couldn't let go of the name.
It's like Nick Meyer using "The Undiscovered Country" for
Star Trek VI. "The Undiscovered Country" refers to death. Which makes sense for where he originally wanted to use the title, in
Star Trek II. But he couldn't let go of using the title. So it went to ST VI, where it made less sense.
I've said it before and I'll say it again: They can't afford to have that many TNG/DS9/VOY characters back. PIC Season 3 was a one-time thing. They couldn't have everyone back even if they wanted to. It's not going to continue happening because it
can't continue happening. The economic realities of show business wouldn't allow for it.
The main focus of
Legacy would be the Enterprise-G crew. If we see characters from other series, it likely will be the same level as what we've seen in other series, as well as the first two seasons of
Picard. I think
Legacy is being specifically singled out, unfairly, before a single frame is even shot.
As far as titles:
"The Next Generation" --> In-universe, it's really the
fifth generation, if you're counting from TOS. But "Star Trek: The Fifth Generation" sounds like a shitty title.
"Deep Space Nine" --> Michael Piller just threw up that name as a placeholder, before they knew it would be the name of the station. But why "Nine"? And it's not "Deep Space" to the Bajorans. It's home.
"This 'wilderness' is my home."
"Strange New Worlds" --> How much of it is strange? How much of it is new? And in some episodes they probably don't even visit worlds. But "Strange New Worlds" makes for a catchy title.
"Discovery" --> The ship is named Discovery. But, except for Burnham discovering the cause of The Burn, and the Discovery crew discovering the 32nd Century in general, they weren't doing that much discovering. Season 5 actually seems like it'll be the season where the series might live up to the title the most (in its purest form) with a treasure hunt.
Technically they discover the Mirror Universe in Season 1, but it was also covered up immediately by Starfleet. And it's something
we as the audience already knew about, so it was a discovery for
them but not for
us. You could throw in discovering Zora too. But, in the first four seasons at least, the title of the series has been a lot more subtle than
"Every week is a new discovery!", which is what someone
could think if they saw the title but didn't know anything else about the series.
So you can't really put that much stock into a title all the time.
