The movie would be better if nobody had sung

Rating: 4/10 (6 November 2019)

The clear criticism is the singing: It was annoying, silly and ridiculous. Positive is the CGI, which was almost realistic. If, instead of singing, you filled the movie with an interesting story, then it would be really good.
I would have rated the movie with much more stars if the story had not been so weak. I like "Ice Age". That's why I watched this movie.
But now I think that this movie is just for kids.
