TOS was made 56 years ago, and it looks fresher than any other Series. A timeless Space Western.
Re: 67 - I like TOS.
And generally TNG other than Seasons 1 and 2. But Nemesis destroyed the Next Generation franchise.
Lately I have been watching VOY. Hated the last episode of the season, as it involved time travel, which seems to be the catch all device when writers can’t figure out a decent plot line. Sometimes it’s okay to just end a series like they did with TOS. The ending for ST:Enterprise was just awful.
DS9 is okay but sort of lost interest in it when it originally came out. May give that a whirl again.
Watched two or three episodes of ST:D - just gave up.
