Huh, didn't realize it was off of Netflix. I used that for my first viewing. Have all of it on Blu now though. Showtime might still have the original series. I know they got it (and the film) on there in the buildup to the new season.
Season one is great, and season two right up through to the reveal is fantastic. After that there's a bit of a slog where the show doesn't know what to do with itself, but it finds its footing again in time for the last stretch of episodes, which really pick things up again in a big way. Fire Walk With Me and the new season are phenomenal.
I hope you enjoy your foray into this long, strange Lynchian nightmare!
