If you want a new universe, might as well create a new universe. Why stick a Star Trek name on it at all then?
I could create a whole new universe that has similar elements to
Star Trek and yet it would allow me the creative freedom to do all sorts of things. The advantage Trek has is a built in audience initially.
I think there is also a perception that
Star Trek is the only space adventure that's really worked on television. It isn't true, but it is a perception. No other property on television has had Trek's reach and sheer quantity of materiel. That can work against you in a number of ways. People can have the idea that nothing but Trek works on TV and the idea that Trek has done everything it could do. Neither of those are true, but they're persistent preconceptions.
It's a false argument because look how many cops and lawyers and medical shows have been done through the decades that are really retelling the same types of stories over and over and over again. Superheroes are no different. How many times has the Batman faced off against the Joker in comics and books and television and films? Over and over again yet people keep going back to see something familiar told in a new way.
Yes, you can do
Star Trek without calling it
Star Trek or you can do
Star Trek in a revised way that allows you the creative freedom that a non Trek creation would allow. But to do so you have to cut the umbilical cord. The Nolan Batman trilogy couldn't have been told if they had adhered to what was established in the Adam West TV series or the Tim Burton films. To tell the story of the Nolan trilogy he had to start from scratch. It's still rcognizably Batman, but told through a new perspective.
Yes, we get that many are wedded to the previous continuity, but studios and general audiences aren't going to care about getting caught up in all that again. Best to start with a clean sheet. Keep some familiar and important elements, but tell the story in a new way. An added advantage of this approach is it doesn't wipe away what was established before. It's simply an alternate take as if set in a sort of parallel universe. Note this is different than what Abrams did who insisted it was the same continuity yet used a time travel gimmick to erase the original timeline. He was saying the original TOS timeline no longer existed. I think it's easy to see how that might piss off some people.
But a clean sheet and updated approach sidesteps that problem. It's no different than being able to enjoy Tim Burton's Batman as well as Chris Nolan's version. They're two seperate things even if there is some familiarity between them.
You know I like revisiting TOS every so often and at the end of it I can pretend those heroes are still out there adventuring and none of the rest has happened. But outside of a fan production no one is going to put TOS back on the screen as it was. So if I want to enjoy truly new adventures in a
Star Trek universe that interests me then it has to be remade from scratch again.
