If it was real Trek and not the Abrams nonsense, I'd subscribe.
Any Star Trek
series on Showtime would make Abrams' "nonsense" look positively canonical by comparison. Think about what Showtime usually goes in for. Not a real good match for Star Trek
, so they'd have to change it to fit, just as Abrams changed Star Trek
to make it more modern-summer-popcorn-movie-friendly (which is why people complain about it being Star Wars-
y - that just means it's calibrated to appeal to the global moviegoing public.)
is going to be changed to fit whatever venue it ends up on - TV, movies, streaming. The TV ecosystem that created the series to date has vanished, and like any species that wants to survive, Star Trek
must adapt or die. Of all the possibilities, Netflix strikes me as the one least prone to making big changes, so if you don't like the idea of change, that's the one to root for.
