DS9 was probably the most interesting of the shows of that time though. It broke several of Roddenberry’s rules:

• plenty of characters had long-running interpersonal gripes and grievances. In TNG everything was returned to status quo after any given episode or two parter. No one really argued with each other, everyone just learned a life lesson and everything was back to normal the next episode. Voyager started with some tension on the ship between the Maquis and the federation crew but that basically stopped after like 5 episodes and it was back to TNG camaraderie.
• it wasn’t on a ship that went travelled about.
• it had long running storylines that lasted several seasons. TNG had a few two parters and that season 1 conspiracy thread with the creepy crawlies taking over the federation but not much beyond that. Voyager had Species 8472 and the Borg and Kazon and whatnot but it was pretty straight adventure of the week stuff most of the time.
• it showed the federation being less than perfect. The federation of DS9 was flawed and made poor decisions at times. Sisko did something so bad once that they dedicated a whole episode to a log entry where he convinces himself he can live with the amoral decision he made to protect the federation, and Section 31 was a whole unit purpose made for dirty work.
• it had Garak. Dude would just straight up murder people, and he was one of the good guys.
• they played baseball. Not blurgball or space-baseball, just straight baseball. It was a shit show of a game, mind you, but they didn’t invent some futuristic sport just because they had to. They just did a baseball.

I think DS9 is the most interesting Trek series of them all.
