Like Ple, I saw the writing on the wall with Lynch's post last year about his emphysema. Having watched it with my FiL I knew his path.
I'm enough of a Lynch fan that I still regret not getting the TV Pilot version of Mulholland Drive at Kim's Video when it was originally conceived as the beginning of a series like Twin Peaks.
I saw Eraserhead on film (the only option then) at a theater. I saw Blue Velvet in its first scandalous release. Saw The Elephant Man and Dune in their theatrical releases. Wild at Heart.
Watched Twin Peaks from its first episode to its last as it aired.
I have an anthology of stories written in the Lynchian universes and style.
Own and have read Lynch's memoir (which is fantastic) and seen his documentary (The Art Life).
Saw a show at Sketchfest last year with the Red Room Orchestra play the music of Twin Peaks with Kyle McLachan and Carl Struycken (the Giant on Twin Peaks) performing.
Yet I would not consider myself a Lynch super fan.
He has, though, completely shaped my visual sense, my cinematic aesthetic, just so much of my cultural intake.
