The TV audience today is predominately female, so you do raise a good point: how is
Star Trek going to interest the female audience, without which, it's not going to survive for long?
One strategy is to cast a female authority figure for captain and have a good-looking guy as second in command. Alfre Woodward fits in very nicely here. (And Bryan Fuller seems to be particularly adept at creating female-skewing shows like
Pushing Daisies, but that may be simply because he generally goes for fantasy rather than sci fi.)
Another strategy is to make an attempt to attract the elusive male audience that has disproportionately abandoned TV altogether.
The Walking Dead has done a great job of this, and I don't think it's a coincidence that it's done so with video-game-style hyper-violence (video games being one of the main reasons TV has lost the male demographic).
The downside is that you have to keep the violence revved up, because when the characters get settled in one place and spend a lot of time talking, the audience gets restive. The first half of this past season took a lot of heat for that, and the ratings did dip some, and then surged for the insanely violent final run of episodes.
Or, to ensure maximum odds of success, combine both strategies. Cast Alfre Woodward as the starship captain with a hot guy as second in command and throw more graphically violent stuff at them than we've ever seen in
Star Trek. Even broadcast is more violent nowadays, and the series would probably end up on cable anyway.
A "dark" show like that doesn't need to be dreary. The Starfleet people could be basically idealistic, a cohesive team built under fire. The female audience will like that. The male audience will like seeing the Borg chopping off arms and legs while their victims thrash around and scream. It's a win-win!
I'm actually quite serious about this - I think a show like that would get a lot of attention (wow,
Star Trek isn't boring anymore!) while not going out of bounds of what the core values of the franchise.
