I am a diehard and I think it would be almost impossible without treading on what came before it. There are events and stories (a ton of them between the series, animated series etc..) that die hard fans followed that you would have to "dance" around constantly. You would have to write in this box. Sure there are writers that could probably do it but it limits creativity.
Not to mention that the #1 thing I heard from die hard fans about going back to the start was ..."what is the point we already know what happens". Now we don't necessarily know what happens and anything is possible.
This is exactly what trek needed to survive. A complete reboot. Die hard Trek fans have proven over the last several years, they are not enough to sustain the franchise any longer. A new generation had to be brought in without all of the baggage of the past. Trek was dying on the vine and even Paramount executives had made comments like if this had failed....Trek might not come back for a very very very long time.
I for one loved this movie, thought it was great but the larger issue of Star Trek dying off as a phenom was IMO just because Gene died and then there wasn't one vision anymore that trumped all others.
TNG was a great follow on, it stood on it's own and moved the whole thing forward, which IMO is the key to Star Trek, it takes place in the future and in the limitless expanses of space so there is IMO no need to really go backwards in it except to recapture nostalgia for fans.
The idea it could ever really get stale going forwards in time is ironic to me, and I agree it was getting stale but that's more due to the competition to take it in different directions.
Voyager was a bad idea, might as well have been lost in space, DS9 was alright but I didn't like the fact it was set on a stationary space station, sorta defeats the point.
Those two killed off the thing worse than anything IMO.
They were IMO sort of cheats, they didn't develop the next flagship captain and crew, that's kinda the essence of Star Trek IMO, the best captain and crew you get to follow along with, you get to meet new ones, they do new stuff, but once you start these offshoots and plot lines out in the Star Trek universe you're losing the essence of the thing IMO.
DS9 wasn't too bad but it was a dead end, that's death to the franchise IMO.
Star Trek has been a tv series but what happens is a new crew is introduced, the backstory takes forever to develop via tv then movies come in and when you do the movies you kill the tv series just by ramping the costs of the actors to the moon.
Once you do movies with one crew you almost have to start a new one on TV, because they're cheap and when they get to the movies stage they're over as a tv series too, the problem with all this is the real time nature of generations causes there to need to be a time lag between series, in the modern world we are too impatient to wait the required time, they tried to stuff the channel and still are trying to do so now by going backwards.
Soon enough there will be a void for a new TV series to go forward and they will I think.
