i'm rewatching DS9 and it REALLY holds up well, i usually go in expecting absolute shitty seasons 1 (TNG and Babylon 5 both had meh season 1s) but DS9 season 1, outside of a few weird baseball references, really was fantastic.
There was that one episode where the crew gets trapped playing basically a video game and that was pretty lulzy
also CBS All Access is going to claw back all the Star Trek shows for its streaming service, right now Netflix USA has DS9, TNG, and a few others on its systems but that will probably go away sometime this year. I of course have rips of everything on my NAS but its nice just streaming over netflix when you can
