TOS: watched it at the grandparents right after "dreaming of jeannie", rarely rewatching
TAS: never seen, and now i can't watch 80s animation anymore, so no nostalgia bonus
TNG: the gold standard, selective rewatching
DS9: hard to swallow at first, but now a fine aged wine, full season rewatching "what i did, was to make cardassia great again"
VOY: soapier version of TNG, selective rewatching
ENT: "hello star wars. i can do prequel too". S4 was awesome though, selective s4 rewatching
DIS: often boring and main character sucks most. but each season had something that made me watch it anyway (s1 mirror universe, s2 capt pike, s3 a new unknown frontier, s4 now it's too late, can't stop anymore)
LOW: comedy version of TNG (includes lots of nostalgia)
SNW: pike is awesome, recasting spock is now okay, rest of the crew is also good, love it
and because some people see it as some kind of trek:
orville: didn't like the combination of actors + comedy as opposed to lower decks
movies:
best movies for me: 4 +8
worst movies: 5 + 10
nu trek (kelvin) is okay
galaxy quest: hilarious
