No, for the average viewer (non-fan) it doesn't make any difference if it's Star Trek. It's about whether or not it's a interesting premise and is it's well produced.
It being Star Trek will get some people to watch the first episode or two, then other factors will kick in.
If the show doesn't catch a buzz on social media, bye bye.This thing going to need what, three plus million viewers to survive? Do you real think a couple of hundred (at most) fans will be able to sink it?
Now if it a pile of poo, and tens of thousand of Trek fans openly denounce it, that's another story.
My hope is that the first couple of episodes are strong enough to create some social media buzz, and I think CBS is being smart by putting DSC on streaming rather than on network television. It's going to come down to how well the show is written and if it can bring in a large enough audience (beyond us die hards).
Game of Thrones apparently has an interesting premise and is well-produced, but I don't watch it because I have no interest in the subject matter. If a non-fan of Star Trek has no interest in the subject matter of DSC, they're not going to watch it no matter how well it's produced.
I'm with you on GOT...I'm completely willing to concede that it's a great show, but having read the books, I have no desire to see some of the graphic violence described there on screen.
