Endwalker is great, but there is a lot. A LOT. Of fluff. Like holy shit a lot of fluff. Also, the second visit to Labyrinthos, apart from the reunion with Moenbryda's parents, is boring as hell and no amount of ill-fitting music is going to fail to remind me of Kholusia v2.0, which was at least somewhat exciting while it was going on
Actually, it's a problem with Labyrinthos as a whole. It seems like a zone I would love but everything in it is fucking boring - story, layout, fish... even the impending doom of the world is just a big ol' "meh, we'll get there with minimal problems since everyone's on board, right?"
Elpis is a pretty cool payoff to the end of ShB though, even if it's not the most amazing of "omg spoiler" zones.

That said, of course there's a lot of cutscenes. A big thematic takeaway I got from the expansion is "we hope you've enjoyed the journey and all its ups and downs." I also don't want to spoil anything from the *post* MSQ (the usual "after the credits roll") but the post-MSQ patches aren't very well received if you try to marathon them. Take them like a week a patch instead of one sitting and they're more digestible.
