Going to be that person and suggest the OP try Voyager.
It seems to be the most accessible of the older shows for younger, newer viewers. It was the most watched of all the classic shows on Netflix.
It covers all the classic tropes and provides endless fodder for memes here.
It’s uneven throughout its entire run, but also has some of the very best episodes ever. New fans really attach to the characters, and there’s no refuting that it unabashedly leaned into the weird.
