So far the trailer is not wowing me, it seems a bit too dark for Star Trek. MAybe they want to emphasise the dark times ahead of them, but Jesus tittyfucking Christ put some more colors into it.
To have a struggling ship and crew it needs to be put in a rather tough spot, explorers when there are things left to explore (TOS, TNG, VOY), or when the Federation is not one of the mightiest powerhouses in existance (DS9).
So setting the show after the Dom Wars is going to be tough without the usual power creep with just another gigantic empire of different species like another Dominion. Let's not talk about the implosion that was the Borg menace.
Why not go back to the times when the Federation was just a hatchling and just about everything in the Alpha Quadrant was more or less terra incognito, with rumores and sightings of monsters (eg Klingons)? Makes sense to me, gives them the chance to fill out some gaps we had so far in the canon (cannons are used to fire at someone).
It offers mystery, exploration and action/war without the powercreep.
As for the characters: As long as they fit into their spots both by personality and capability i don't give a damn about their skin color, gender, religion or eating habits. If they however get preachy about any 1 of those things .... there's the airlock, out you go.
Quick example: Jeffrey Sinclair and John Sheridan may have commanded B5, but no one ever questioned Cmdr. Ivanova unless he wanted to breath space. She never preached about her gender or religion (although she gets a whole episode to sit shivat), made at best quibs about russian stereotypes, and otherwise did an outstanding job of keeping B5 running. She was defined by her actions and attitude, the rest was part of her but did not make or define her.
Oh, and if they trek through the Alpha Quadrant ... please do some noticeable pit stops, carry over scars and damages from previous episodes (not just as a plot hook to go looking for a new better do-hicky), and story lines that go over several episodes if not a whole season. TOS and TNG episodes you can watch in nearly whatever line-up you want, their episodes are so interchangably it sucks FOR ME quite a lot of fun out of it. I so much more prefer DS9 with a running story.
