Hollywood makes movies to make money. Given the current state of the motion picture industry, a "Great BIG Trek" a la Abrams makes sense. But as Christopher Nolan's Batman trilogy shows, that in no way means you have to throw away quality of storytelling. And I would argue that trilogy will end up more profitable than the Abrams Trek
s in the long run.
Having said that, if JJ Abrams goes off to do Star Wars
and leaves Trek
behind, then somebody else can pick up the reigns and do something better with his alternate timeline. It isn't as if all the eps of TOS were high quality, yet all things wonderful in TNG, DS9, VOY and ENT proceeded from that!
From what I understand, the film industry is in serious flux. With the price of tickets what they are, and competition so increasingly diverse and readily accessible, we'll see what happens. If making three or four Treks for the internet costs a tenth as much as STID yet makes one quarter the profit, then we're talking a very different business plan for exploiting the franchise, which in turn impacts the possibilities quite a lot.
Such a scenario might well provide for alternate series/films in different continuities, each with a distinct "look."
