I liked Season 1. But Season 2 was very hit and miss. Mostly miss for the last half of the 2nd season.
If you haven't seen the movie "Twin Peaks: Fire Walk With Me", don't. It is a steaming pile of turd.
I actually love the movie. The scene in the bar is very hypnotic, and the whole story is pretty depressing. The movie overall is much more Lynchian than the series is, though, so I can see why some might not like it very much. I would agree, though, that the series (especially the first season) is even better. I think it's probably my favorite TV series of all time.
"Twin Peaks: The Entire Mystery" (2014) contains 90 minutes of edited footage shot for "Fire walk with me" that fleshes out the story and explains things for most of the original characters.
I wish they would release a cut of it with The Missing Pieces
edited in, because I felt a lot of those scenes would have added to the movie and explained some things better.
EDIT: My sister once wanted to borrow the series from me, but she took home FWWM by mistake. Needless to say she was a little confused, and she's never asked to see the series since. }|:op
