Yeah, S2 onward. But unlike other shows with long runs I've simply lost interest in, at least it will accommodate a casual watching pattern without losing out on anything. The principals all have other work, so it's not like they're desperately prolong it it to eek out a living, so they come and go as well.
Later seasons had their moments, but the first was the most authentic in terms of sticking to the premise, and not veering toward stepping over the line into silliness, or eventually having that funny smell like something past its expiration date. The attempted spinoff without Kiefer can be skipped entirely.
