The musical elements in particular were one of the points I didn't like. From the moment the very first character started singing, most of them felt shoehorned in.
Also wasn't a fan of how they used musical numbers in place of plot development a few times to get major results or to change characters' minds on things without actually having to do anything except use the power of song to pull it all off.
Compare how the music played into that big moment at the end for instance to how the music and singing works here:
You can see the lyrics in this clip - the song is very important to what's happening but it's also not the vehicle by which she defeats Te Kā as you can see the monster continuing to barrel at first angrily and then desperately towards her while she sings right up until it gets there. It's very much not the power of music defeating the villain; it's just her coming to a realization about her adversary and revealing that the monster was never actually a monster that wins the day.
I find it truly baffling that the same studio made both of these movies.
Yeah I think I would have liked the opening number a little more had we not just seen a much better version of it in Encanto.
