Battlestar Galactica had to siphon in a lot of sex, politics and unnecessary plot twists to have a decent run. Not sure I want that for Trek, but sci-fi can still work on modern TV if it is gritty enough, over-acted and complete with an assortment of fan service, bomb diffusing and vomit-inducing love stories.
Meh I think politics and plot twists was the entire premise of BSG. It was lost meets west wing, and there seems to be zero attempt to hide this. They pretty much went around trying to reenforce the west wing concept in many interviews.
I think the gritty dark thing is the wrong direction. You cant just copy whats popular and expect to be popular.
You have to diverge which is partially the attraction..
At the same time, character development is key. You cant have one dimensional characters that have no struggles.
The advantage that star trek has is they do not need to be struggling with other people as space has plenty of room conflict. The amount of internal conflict caused by extreme environments, and the internal struggle with dealing with fear is so great for trek.
I think the survival aspect of space needs to be explored, and Im not talking about a wandering nomads type deal. Moreso characters trying to navigate great dangers. The redshirts side of things I think would be best for that reason.
Sex is a complicated matter. I think having a show with people that are essentially asexual is just so backwards and out of touch its laughable.
At the same time there is no need for cheezy teasing(sex kitten in spandex) nor is their a need a love story that is overly sappy. The starbuck arc is a prime example of a character that is clearly sexual but neither sappy or stupid tease. People in general are attracted to strong female characters its a common theme that people gravitate too since atleast the alien movies came about.
The key is you have to deal with adult content in mature adult ways. And narrate it in a way that it actually feels unique.
In short Sex sells, but its more economical to be fine dining, than fast food.
Its also important to understand the kind of characters are drawn todays audience are drawn too.
House, neil degrasse tyson, cumberbach dude , the breaking bad lead, tyrion from GoT, gauis balter, michael fasbender sheldon from big band etc all show characters that directly relate to todays taste.
People like a mix of intelligence, arrogance, sophisticaton with a capacity for witty humor. This I think is why spock kirk and bones are so dam attractive, and why ENT, VOY were firing absolute zeroes.
This is why I think focusing on a crew of lower deck officers, all believing they are the best, trying to survive the worst would be so appealing.
