It was a worthy follow-up to the first film, although I didn't think it was quite as good.
In some ways, it improved. It was beautiful, for one thing - more variety in scenery. Some truly beautiful shots.
But I felt they were a little heavier on the comic relief this time and it didn't work for me: Kristoff's music video moment really did not work for me. Like, at all.
I did really enjoy it overall though!
