Got partway, don't plan to finish for some reason. Either the quality dropped (The Simpsons), or I really wanted to love them but they just didn't click for me (Buffy), or what I saw was interesting, but not enough to invest time in the whole thing (The Borgias).
An array of some of my favourite TV shows including throw-backs and more recent programming that no longer air. One or two series didn't end as phenomenally as they started, but all of them kept me watching to the end :-).
