Darkness shouldn't be the broader tone of a new Star Trek show. That's not what's made Trek so popular for almost 50 years, and it's not going to carry an entire series anyway.
Give us an optimistic and hopeful message set against a backdrop of galactic uncertainty. Make the cosmos seem mysterious and wondrous again.
Set it about 30-40 years after the destruction of Romulus.
Give us a swashbuckling captain -- a flawed but noble man that an audience (particularly a young or young-adult audience) can enjoy following.
Give us an intelligent, personable, and diverse crew. They should both compliment and complicate their own relationships with each other and the show itself.
Give us a cool new ship.
Don't hit people over the head with a specific sociopolitical agenda. Yawn, change the channel. Employ subtlety, and it's more effective anyway.
Be serialized and
episodic. They're not mutually exclusive. In a story this big, with this many possibilities, stop limiting yourself.
Stop relying on all the familiar villains and locations. Incorporate them, but don't depend on them. Create the next
Make it a new adventure
