This is a satisfying conclusion to the season's arc, but leaves a lot of unanswered questions.

We get Rory back and his reunion with Amy is very nice to see (though Amy's behavior during the wedding is like wtf).

We get a lot of fun vortex manipulator shenanigans, normally the show stays away from this kind of thing but the universe dying provides a good excuse for it to work, and the plot threads come together nicely.
