I (once again) recently watched 'China Beach' (which I own on DVD)--if you've never watched it, it is truly magnificent. Setting is primarily Vietnam, with the story of the conflict mostly told by and seen through the eyes of the nurses at the Five&Dime (510th evac hospital near Da Nang). So many outstanding actors--and the writing is outstanding as well. I watched it when it was on TV in the 80's, but it really resonates and hits me much harder all these years later. May be able to find it through your local library, as it is not streaming or available on any network, as far as I know. This is probably my favorite TV show of all time, with 'The Americans' running second.
Am in the middle of re-watching 'Dark Shadows' (own this set also), which was a favorite of most kids in the late 60's. At 1200 or so episodes, it takes some dedication, but I am really enjoying it. Using a 'live on tape' method, many things did go wrong, and actors flubbed lines with regularity, but the show feels more like a play than a network show. Dan Curtis also directed the actors to bring over-the-top performances to the action. Love that many of the stories are influenced by the Brontes, Shakespeare, and other classics with that gothic romance vibe.
