You’ve got me there, I loved DS9. But then, that series wasn’t particularly gloomy, although it had its moments of gloom.
And it’s probably true that the war aspect of it is less what bothers me than the lack of anything new. DS9 had the Dominion, the shape changers, the Cardassians, the Jem’Hadar and a lot of other really cool new concepts for alien races and civilisations. Discovery apparently has the Klingons, who have been done to death a thousand times.
Hm… … … yeah, okay, I have to say I would be fine with a war-based Trek show that takes place, say, one generation after Voyager.
