Rewatching this now, it's even better on second viewing. It is like a piece of nostalgia to a different political era on both sides. Full of great story lines, great cast, well written characters…but most importantly, actual optimism which is in short political supply right now from any and all sides.
What's funny though is that I am rewatching Lost as well. With Lost I only remember the really high level details and very little of the actual plot lines, with the WW I remember the plot and details of every episode I've watched so far, even down to the dialogue and how they shot scenes. It all stuck with me because it's so well made I guess.
