DS9 raised the bar so high that it's past the Oort cloud. I've watched everything up to Enterprise and I will say that I enjoyed all of them despite their flaws. I tried watching the newer trek series: lower decks, discovery and picard. Lower decks was an instant turn-off and I fell asleep on the first episodes of the other two, twice. The free month of paramount ran out before I bothered trying to watch them again. I should give them a go one day.
