The industry and the public will never be more tolerant of space opera. The industry is going towards greater division of mainstream vs niche programming, and doesn't need space opera, now or ever, even in the niche space. There are lots of niches they can opt for instead - Westerns, horror, supernatural, superhero, dystopian sci fi, murder mystery, high fantasy, etc.
The public likes the stuff it's trained to like. Give the public a million cops shows and the public likes cop shows. Give the public no space operas, and they forget space operas exist.
The way
Star Trek will get back on TV is through the concerted efforts of a producer or team who are determined to make it happen, despite the considerable obstacles. These folks need to be established in the TV biz so they will be listened to. They need to have an understanding of the pitfalls and opportunities of the various channels where a series could run, and craft a series intelligently to minimize the pitfalls and maximize the opportunities.
And it wouldn't hurt for them to bring in international financing to mitigate the risk. A
Star Trek series should be a strong seller overseas (sci fi shows usually do well and
Star Trek is a globally known brand name).
After that, the marketing campaign will generate demand for the new
Star Trek series, just like it did with the Abrams movie, which became a box office champ by going beyond the traditional Trekkie crowd. If the series is well matched to the channel it airs on, then it should be able to draw from existing viewers of that channel, which are easy to market to. You just show ads for the
Star Trek series as bumpers on the shows they already watch.
Take care of all this, and it doesn't matter what the content of the show is. Klingons or no Klingons, Abrams U or Prime U, that stuff is really beside the point. Many different approaches to
Star Trek could be made to work, as long as the people behind it have clout and business savvy to get the show greenlighted in the first place.
I don't want to see a low budget, cheap looking Star Trek on some obscure channel.
Why do you think that would happen? Are you talking about SyFy? I wouldn't expect
Star Trek to end up there at all. Showtime would have the budget to do a good job, though.
