1.) A clean reboot - what we got was a mess that massively altered the "prime" universe as well as the "altered" one.
They didn't alter the past of the prime universe. Canon was preserved.
Yes, canon was perserved. But since Romulus was destroyed in the "prime" universe, it's been drastically changed.
I'm not wild about Romulus going kablooey. Vulcan being destroyed seems like less of a problem for good stories than Romulus being destroyed - you gotta have strong villains.
But even then, some fancy footwork could repair matters some. The Romulans had plenty of advance warning about the supernova - those things don't just pop up outta the clear blue sky - so they could have evacuated a good portion of their population and could establish a colony elsewhere, and rebuild their strength. The Romulans might be even more interesting, considering they are still crafty and formidable people, and are now mad as hornets.
That is, if and when we ever return to the primeverse for TV or movies.
I'd like to recapture that "strange new world" and/or "where no man has gone before" sensibility. I want to get away from familiar territory and feel like we're "out there" again.
We'll have disagree there. I find that Trek is at it's best when it builds on familiar terrority. The whole "strange new worlds" and "where no man has gone before" concepts never quite worked for me.
If you actually look at what TOS is about, it's mostly not about exploration anyway. It's Kirk & the gang patrolling and defending the Federation, plus getting into trouble, plus personal stories. The actual business of exploration - mapping star systems for instance - would be rather dull and doesn't require a close-up visit by a starship anyway.
Investigating alien species on a new world does require a close-up visit, by scientists, but you don't just fly away after meeting the natives. You stick around to make observations, which would require decades or even centuries.
Real explorers would establish outposts on every new world, and probably do, after the Enterprise has made first contact. But the Enterprise's job is not science; it's to make sure things are safe for the real explorers who arrive in their wake.
The Enterprise wasn't exploring in the scientific sense. It was sussing out opportunities for the Federation, in the diplomatic and political sense. Their attitude towards new worlds was not "can I write a scholarly paper on these people" but "would these people be good Federation allies/are they a threat/are there trading opportunities?" All you have to do is look at ENT to see how dull and pointless hit-and-run exploration is, minus the Federation to give it purpose. It ends up being space tourism.
I don't believe Star Trek belongs on the big screen - that goes for any of the series. You have to compromise too much of what Star Trek is to make it work there.
I think it belongs on TV, too. And I'd like to see a return to what TOS really used to be about - patrolling and defending the Federation, and exploring with the purpose of finding allies and discovering threats.
Star Trek should always be on the frontiers of the Federation, because that's where the threats and opportunities are. But it shouldn't wander too far away, or it loses purpose.
a) Spock would have been a pure Vulcan. A Human-Vulcan hybrid (assuming we stick with TOS physiological differences) is about as realistic as a Human-Artichoke hybrid.
That's a great way to ruin the character! Spock is Spock
because he's an outsider everywhere he goes. Just because his birth is unlikely means nothing - faster than light travel is unlikely. A device like the transporter ever being built is highly unlikely, and if it were, it would kill the people it transports and nobody would use it. By the 23rd C, I'd bet a Human-Artichoke hybrid will be possible (probably possible long before then, hopefully not in our lifetimes!

) but a lot of the tech on
Star Trek will never be possible.
