This makes me realize that I'm not sure how much (if any) of the last season I've actually seen ... and none of the reboot, but I think with the original show, it was mainly an issue of not being able to get my hands on the final season - this was back in the era when downloading TV episodes was actually pretty difficult - and then just never really getting back into it enough to watch all the way through. I've rewatched parts of the first few seasons a couple of times over the years, but nothing from the late seasons, I think.

I do remember every time I rewatched some episodes I found myself noticing that thing you mentioned, how it has aged very well and very gracefully. Some of the writing is dated now, but it's still funny and often feels more contemporary than you'd expect. The low-budget nature of the show is probably a feature, not a (star?)bug, since cheap model f/x look pretty much the same no matter when they're being made.
