No idea how it would hold up on a second rewatch but I didn't get around to watching it till in the 2010's and it held up pretty well then.

It's got some pretty compelling story arcs and character development that hold up well. And the campiness is leaned into enough that it feels good as part of the show. There's some filler episodes but that's kind of expected with a show with that much run time(the concept of shorter seasons that just focused on the story arc was still pretty foreign)

It definitely went beyond just kill random villain of the week and had some themes that are still relevant today and it dealt with them pretty well for a show ostensibly aimed at teenagers.
