At this point, a Star Trek series, made as close to the original concepts as current trends and tastes allow, would probably work best on Fox.
Problem: Fox has no patience with struggling shows, so part of any deal would have to include a guarantee for a full season, maybe two, and a timeslot early in the week. Maybe not Mondays at 8, but anywhere but that Friday night death slot.
The real problem is convincing CBS to make a show for FOX. Also, just because of all the broadcast networks, FOX is the least bad option, doesn't mean any of them are good options.
As for FOX's reputed impatience for sci fi series, I think they've learned their lesson. And the Friday night death slot can be a good place for a sci fi show. Sure, ratings are lower, but expectations are also lower. They have to put something on Friday and if they expect ratings to suck, maybe they won't be so quick to cancel a low-rated show.
That makes no sense. Why would Star Trek need to "vindicate" itself just because it's well known? It won't need to do any better or worse than Generic Space Opera - assuming either series were ever made.A high-profile, high-risk project (as attempting Trek on tv again would surely be) is expected to vindicate itself with a measurable increase in viewership.
Budget is one factor. Others are: how well it holds the lead-in numbers, how well it does compared with the previous occupant of that time slot, and how well it does compared with the standards for wherever it is airing. Or to boil it down, it needs to get "good ratings," and to do that, it needs to attract the viewers of the channel where it is airing, since they will be the easiest to attract (after Trekkies, who don't need to be marketed to as much). Assuming its budget isn't through the roof, if it does as well as average for that channel, it should do okay.Star Trek would be expected to perform in accordance with its budget, wherever it airs.
Premium cable is a different horse race than broadcast and basic cable because new subscribers matter in addition to Nielsens (and where are you getting the new subscribers figures from? Cable channels usually don't like to release those figures.)HBO are happy with Game of Thrones because subscriptions went up. AMC are happy with Walking Dead because of a colossal increase in ratings as compared to their usual fare.
I'd hate for Star Trek to be treated as shabbily as AMC is treating The Walking Dead. It's a ratings hit, but its budget is being given to that overrated bore-fest Mad Men. No wonder Darabont bailed on the whole thing.
