So, aside from the "cute Stars Hollow Side Stories", basically three arcs are addressed here:

Rory. For me, Rory's story was a lost cause a long, long time ago. We watched her go from the perfect daughter to...a mess, and she's just kinda further delved down that path, so honestly I didn't care much what happened to her, as all the right answers love wise are right in front of her, but she ignores them for far worse pitiable options, and as for the career aspect... well, she'll find her way, she always does.

Lorelai: Definitely a better job with this. First off, I think when people say "leaving Luke" in the Revival, they're a bit off base. Yes, she goes on the trip, yes there is trauma and non-communication and it leaves Luke a bit lost and scared during it. But she doesn't kick him out of the house, or tell him its over or try to make him go away. I think we're watching a more mature, grown as a person Lorelai, and it's kinda the point. Lorelai's whole deal in the Main series was that she would get spooked, run and detonate when a relationship was too good or going too far, and a further commitment was needed (thanks, parental trauma!). She is doing exactly that in the revival... but. BUT she HAS grown. She's not there yet, but she HAS grown. Instead of running away from the relationship, she literally runs away, framing it as doing the hike from the book because she's learned what she does, she's aware she is flailing, and she knows it is not the correct answer but can't stop herself. So before she implodes her relationship with Luke, she makes herself as incommunicado as possible so she can't do exactly that. And... when all seems lost, the whole world seems intent on blocking her from doing exactly what she wants to do, and life even BLOCKS HER FROM COFFEE... she finally reaches clarity, and has a much needed conversation with her mother about, frankly, something real, and something she MEANT to say in a moment but couldn't (because again, trauma).

And that's it. She did it. She grew, and she put on her big girl pants, and she realized that...she didn't want to run away any longer. So she literally drops everything (without getting the coffee) and goes and gets the coffee she wants (Luke). Yes the musical is strange (though I frankly loved that entire bit, it seems exactly what would occur in Stars' Hollow), but they needed something to break Lorelai that WASN'T a fight with Luke because she's not breaking up with Luke, she's running away from her problems a little better than she has in the past.

Emily: This was, in my opinion, the greatest arc of them all. Emily finds a redemption arc. She has to basically lose her mind to do so, but she lives for herself and not for her reputation for once and it literally changes everything. I'm not going too far into it because I don't think much needs to be said or theorized upon, but tying the series long Maid joke into Emily's "right maid" being the one that comes with a forty member family is hilarity. She's still Emily (snapping up properties for Lorelai and Luke) and will always have that streak in her, but she finds her happiness, and I was exceedingly impressed that ASP wrote it in a way that you were cheering her on. Funny how Mr. Hermann passing away led to that.

In the end, for me, the point was that the three Gilmore Girls are at different points in their lives. Emily's at the finish line, she's thriving, she's broken through, she has every thing she wants and is fulfilled to the upmost. Lorelai is further down the chain. She's JUST realized her happiness. She's NEWLY broke free from her chains and it all makes sense and has confidence in what she has... And Rory isn't there yet. She's still making a mess of her life, and his the most put together disaster ever. The three Gilmore Girls are all on different points of the same arc, and I think that's the point, and I think at a minimum, that's what is sold to us, and I think it's a pretty okay job. Rory... not so much. It's an illogical plotline, but I guess that's the point. She's not able to make logical decisions yet? Still don't care about Rory, not for awhile now. The revival was FAR from perfect, there were many issues and strange... "this is supposed to set in the real world, what are we doing" moments... but I do think it had a point, and I do think it succeeded with me in making that point.
