To be fair, you COULD finish the 2017 Return season. I feel that the ending reveal of >!Carrie Page and her subsequent spooky road trip!< opens up an "ouroboros"-style ending where you can just keep going back to the beginning and it'd still carry the proper momentum of a good story.

Then since there are callbacks to it in the last couple of episodes, you could hunt down the 3.5hr Q2 fanedit of Fire Walk With Me and watch that. It also serves as the prologue to the 90s original series.

For some reason I feel that the light-hearted meandering spirit of S2's back half would be a breath-taking palette cleanser after frontloading your TP experience with the more intense dramatic turns of The Return and the movie. I'm interested to see how that works out.

TL;DR: The Return, Q2 FWWM, S1, S2.
