I thought lt was a bad idea to destroy Romulus/Remus in the Prime universe and worse to destroy Vulcan, even if it is not merely to put his stamp on these movies.
It wasn't just an ego trip. More likely, they wanted to make it clear, beyond the shadow of a doubt, that the old "canon" had been blown to smithereens and wasn't coming back.
TNG managed to "reboot" the franchise without destroying Mr. Spock's homeworld. And with a brand new cast of characters too. That took balls. Going over old ground with Kirk and Khan is playing it safe. Even preserving the Prime universe is playing it safe to an extent. It's Star Trek. Anything can happen. In 10 years we could be back in the Prime universe with the Abrams movies being discarded because the people who grew up watching TNG want to see that universe again as it's "their" Star Trek. 20 years after that maybe the Abrams universe will become a nostalgic memory and the current generation of Trek fans will want a return to that. Both universes are robbed of an important planet either way.
(Frankly, ENTERPRISE could save themselves a lot of trouble if they'd just booted the "canon" out the airlock in Episode One.)
Agreed. And Abrams should have just rebooted the whole thing too. Or better yet created a brand new crew in a different century like TNG did. That was originality and daring from Roddenberry that may have not payed off but it did in the end.
We can quibble about whether revisiting Khan was a good idea, but the fact remains that, with Vulcan gone, the future of the timeline has irrevocably changed so that we don't know whether Kirk is going to be killed by Soran, or whether Sulu becomes captain of the Excelsior, or even if ANY of the events of the latter-day series or movies will happen in this new timeline.
And yet all these people still ended up on the Starship Enterprise together. This is not a brave reboot of the franchise. It's hedging its bets my keeping one foot in the past with the illusion that one foot is in the future. TNG was fresh, DS9 was fresh (space station), even the idea of Voyager was fresh, for Star Trek at least, even if it was squandered by the end of the pilot. Abrams movies and the show Enterprise are guilty of dressing up a well worn franchise in shiney new clothes and passing it off as something fresh in my opinion.
If they want to have Chris Pine and Zachary Quinto fight the Borg, it's doable because TNG takes place in an alternate timeline now, so we don't have to worry about how things played before.
You could look at that 2 ways. They don't have to worry about the continuity but they can still benefit from popular villains like Khan and the Borg instead of creating their own. TOS gave us Vulcans, Klingons and Romulans, TNG gave us the Borg and the Cardassian, DS9 gave us the Dominion, Voyager (for all its flaws) gave us Species 8472, the Hirogen, the Vidiians, and (may the Prophets forgive them) the Kazon. Even Enterprise, as misguided as this was, came up with the Xindi and the Suliban. What has JJ Abrams given us that's new? Scotty's little pal?
And as for preserving Romulus for the sake of the Prime Universe . . . let's be realistic here. Nobody reboots a franchise with the expectation that they might go back to the old version someday, so whether Romulus exists in the old universe is purely academic at this point, as least as far as movies and TV are concerned.
Nobody reboots a franchise by stating explicitly that the old continuity is still in tact either. It seems they want to have their cake and eat it. Look at the rumours of Shatner coming back in Part 3. It's either look to the future and do your own thing or keep drawing from the past which is what Abrams has done so far. I agree he should have just rebooted the whole thing. There can't be that many people out there in the grand scheme of things who care whether the other incarnations still exist or not. I know that's ironic coming after this novel I've written

but just because somthing is rebooted it doesn't mean what came before isn't still out there to be enjoyed or can't be revisited ever again. The destruction of Romulus was not a great idea in my opinion. If the old franchise is "blown to pieces" then leave it as you found it and concentrate on the reboot.
