Looks like it was made only to cash in on the success of the original - and that is fine but a movie still needs to have a story. It seems that the story teller went on leave and delegated to the proof reader. Songs were too many and too boring. The movie seems like a merchandising effort with neither soul nor brains. Doesn't appear to have put in much effort. And somehow knew that there will be no Frozen 3 so why bother? Eminently forgettable.
You won't miss much if you don't go.
