I'm working my way through The West Wing on Netflix. I haven't seen many of these episodes since they originally aired (for whatever reason, The West Wing somehow did not have a long life in syndication), and I've realized a couple of things:
a) if airing right now, this would be one of the best shows on television,
b) this country, as different as it is, is not so different than it was in 1999.
There's been episodes delving into gun control, preemptive military strikes, the efficacy and morality of terrorism (and our response to it), the internet, and more. The list goes on.
It is, easily, as good as I remember, and without a doubt, one of the top 5 TV dramas of all time.
Aside from some visible outdated technology, there's little to place this show in the early 2000s. It could air today and no one would be the wiser.
Hell, maybe NBC should think about that.
