I'm very early into season 2... so far, I give this series a very solid A. It's actually held up fairly well over 2 decades other than some technology... but the writing is excellent and the casting (overall) is really good. For a show, they did a pretty good job of keeping things in the realm of realism (especially compared to most all other shows) while also not making it too boring or inside baseball. Glad I finally jumped in on it.
