If you have kids, this won’t be a terrible time. The singing is fine, the song choices are better than the first movie, but there is no plot. I believe that the goal of this movie was to pack as many songs into the run time as possible. There are more songs than plot and that is fine. I don’t see this movie lasting very long because of its lack of substance. The movie is essentially a playlist with animals singing or dancing to them. Nothing award-winning, but entertaining enough for kids.
I wouldn’t go out of my way to watch this unless your kids want to watch this. For everyone, even if you like the first movie, it is lazy and done to sell a soundtrack. It isn’t bad by any means, but I wouldn’t spend the money to watch this unless necessary. If you do have to watch it, it’s not going to be a dreadful experience at least.
