I notice an absence of Babylon 5 in your list I don't know how it has aged because I watched it when it first broadcast, but it was amazing then.
You say Dr Who, but have you watched all of them? Try and get some Tom Baker series, The Face of Evil, Genesis of the Daleks, The Robots of Death, City of Death, and The Pirate Planet are all pretty good ones.
If you haven't seen Deadwood or The Wire, these two shows deserve the hype they get. Truly superb television those two. Al Swearengen and Omar Little are the two of the greatest anti-heroes ever written.
West Wing yes.
Twin Peaks yes.
