In Trekpertise's 'The Trek Not Taken', JMS's is touted as 'hard scifi'...but I can't find anything about that. Just that it'll be with the original crew ensemble.
"We will keep the classic silhouette of the Enterprise, but fit her out with a level of amazing
technology based on what the best and the brightest minds tell us the future will look like in
200 years. Tricorders and communicators were predicted by the original Trek and are
already upon us in GPS technology and cell phones. What new wonders can we predict for
the future knowing what we know now?"
Doesn't ring 'hard scifi' to me (right now, as far as I
know, the hardest scifi that is soft enough for Star Trek level shenanigans will produce a ship more akin to the
XCV-330, not the classic silhouette of the Enterprise NCC-1701), it just seems like it's going to be more akin to 'We're going to try to future proof the props' - which TNG has already basically done?
To me, "Hard Scifi" is great! It's alluring. But in media, I've come to realise, it needs to be a dressing, a devil-is-in-the-details sort of thing. Technobabble is to be avoided, the focus on tech needs to be minimised, it's all about the characters - just like many a good piece of fiction should be, even a technothriller or world-work.
Mixed with a Space-Opera, what comes to mind is stuff like wearing suits when going to any new planet, lots of decontamination (and no, not the fan-servicey ENT kind). Lots of weird planets, different atmospheres, different Gs , lots of weird species, lots of hurdles in communications, that sort of thing. (One thing NuTrek got right was shoving that sort of stuff in there).
It could be done but at that point just make a new show; focus on the Local Bubble and have ring ships and all that, CGI aliens that aren't humanoid being the norm, lots of different strains of humanity going which way, radiators glowing dull red, stuff like that.
Everything else I'm reading about JMS's proposal is...retreading on already walked ground and linking things together that should be left well enough alone, such as TNG's the Chase, TOS's doomsday machine, the like. I'm also just not that interested in Young Kirk, Young Spock, etc. We saw that with the new movies. Didn't grab me then, JMS's wouldn't now, or in '06.
I'm gleaning all of this from
this document.
