Syndication is also called reruns, when the show is rerun out of order on TV at a standard Timeslot. Like for me TNG was on every night at 7pm M-F. It was shown in random order as far as I know with I believe them skipping less popular episodes, I honestly never noticed if they did hits for a bit then did a rerun through it or what.

The first season of TNG is considered weak as a heads up, similar for DS9 though DS9 has some bangers in S1, TNG is mostly weak. That said if you like it, you’ll LOVE the rest.

SNW is fantastic and I really recommend it, it is certainly New Trek but it’s a MUCH better successor to the legacy than Discovery.
