Well, I'm a little late to this thread, but I'm in the middle of watching Twin Peaks right now, so I'm glad this got revived so I can contribute to it.
Granted, while I say I'm watching it right now... what I really mean is that I was hooked for a while, got a few episodes past the part where the Laura Palmer murder is solved, and then I got bored and lost interest. Hopefully I'll come back to it soon. But up until that point, this show was really hooking me like no other. I've never had a show make me feel so simultaneously amused and ashamed of myself for being amused than the funeral scene where Leland throws himself on the casket.
Also: "This must be where pies go when they die." Love that line.
