This was... alright. I didn't care much for the story, especially the way Kristoff's story went nowhere, how the kingdom was spared, and how little Anna becoming the new queen was earned. Songs were good, but it's true that nothing's really sticking out in my head right now.
Something that stood out to me is how similar the story beats are to Tangled: the Series. There, Eugene is trying to figure out how to propose to Rapunzel, and Rapunzel gets called by a magical force to travel outside the kingdom. Said magical force is also destroying the kingdom. However, Eugene actually does propose to Rapunzel... and gets rejected, because that isn't what she's looking for right now, and we see their relationship develop from there.
Also, I don't know, I feel like the lore additions to Frozen didn't work as well as they did in Tangled. Like in Tangled, the series made me buy the idea that there were ghosts and sorcerers and sea serpents and giant robots lurking off screen from the first movie. With Frozen 2, all these nature spirits hanging around in a forest not too far from Arendale just didn't seem like something that would come out of the first movie.
