I have reached DS9 in my rewatch of the Star Trek I grew up with, Next Generation, DS9, Voyager. I’d forgotten how hard it goes from the outset, and how well they used season 6 of TNG to lay the groundwork.
(Sorry Original Series fans, I tried watching that as well but I’m afraid it’s aged like a pint of milk on a summer’s day, especially the “HD” version where it’s incredibly obvious everything is made of polystyrene)
