A old person once told me back in the year 2014 before we The Expanse and Star Trek Discovery the reason why we didn't have a big space show was because a certain demographic was watching more TV. I thought he was full of crap! It was long thought that fantasy was a genre once thought reserved for geeks but Game of Thrones has garnered a huge audience. Perhaps a well written space opera with a huge budget could appeal to a diverse audience.
What would a space opera that would appeal to people who watch Star Wars movies and are not interested in Star Trek or the Star Wars EU books and video games be like?
Would it have aliens?
FTL space travel?
Would it have relevant themes? For example a sci fi universe where there is a star cluster with interstellar powers that are like America and Russia. Along with these huge interstellar empires there would be lots of solar systems that are independent of these superpowers and one of the solar systems is in chaos and is experiencing a civil war fought by different factions. An agent sent by an ancient advanced society like the culture is sent to diffuse the situation before it spirals into interstellar nuclear war.
Or would it be Mass Effect/Babylon 5 style with a All American military spaceship commander uniting the galaxy against an ancient threat?
