WARNING: If you haven't watched the latest episode from season 3, spoilers abound.

FAQ:
>I want to get into Twin Peaks, in which order should I watch it?
American Pilot (the one that lasts ~1h30m) + Season 1 > Season 2 > Fire Walk With Me > The Missing Pieces > read Secret History of Twin Peaks (optional, but the new show has referenced a ton of stuff from it already, so it's actually advisable to read it) > Season 3.
You can also check out the International Version/Pilot/Movie (1h52m), which was put together in case the show didn't take off. The first hour and a half are the same as the American Pilot, however, the last 20 or so minutes have scenes from episode 3 and new material that didn't make the show or was shortened. DO NOT watch this before you have finished season 2. It doesn't spoil, but it also kinda does. Mainly it will confuse you if you watch it first.
>I have never watched Twin Peaks, can I start with Season 3?
No.*
>I have not watched Season 2, can I skip to Season 3?
No.*
>But anon I've heard Season 2 dips in quality a lot after the first 9 episodes and then comes back to quality at around episode 17-22
This is true, but ideally you should still watch it all. You can skip the James-out-of-town scenes safely.
>I have not watched Fire Walk with Me, can I skip to Season 3?
No.*
>I watched the new episodes without ever watching any of the old stuff and still enjoyed it. You mad?
No.
>Do I need to read the books?
No. The Secret History of Twin Peaks might be an exception since a ton of stuff from the book has referenced things that happened on the new show, but really it comes down to whether you want to read it or not. It isn't mandatory. The other books are even less relevant, however you might just enjoy them anyway. Just don't expect other anons to have read them.
>Has everything leaked?
No. Do not fall for the Croatia meme.
>When do the episodes air?

They're all here, just scroll down to the third season.

*By "No" we mean "You shouldn't if you actually want to enjoy the series and understand the motifs/story"
