Loved this more than the first one even through a few plot holes and bad songs.
So the character development is kinda strange in the beginning. They seem to have regressed since the first movie. But it makes sense later when you see each character goes through a transition. Anna with the whole codependency thing with her sister, elsa and really digging deeper to find herself, oalf excepting change, and kristoff with the challenge of love and his place in a very complicated family.
It really pulls together at the end once you get through the bumps. I enjoyed the family secrets and continuous action to keep the movie moving along.
The music was ... ok nothing that made you want to sing it over and over again but a couple of songs were moving. Sorry you peaked at let it go.
Overall I really enjoyed the movie and want to see it again.
