Twin Peaks, the original run. I watched each episode twice a week when it first aired, then several times once I had it on VHS (including a 24hr marathon with my friends), and then I’ve watched it about 3 or 4 times on DVD. However this has involved fast forwarding through some of the storylines I don’t like in the 2nd season (mostly James & Evelyn,little Nicky, and a lot of the Nadine and Mike stuff). I’ve only watched the 3rd season once so far, it’s long, and quite intense, and I haven’t had the head space and time I would like to dedicate to it when I go back into it again.
