Here are some quick bullet points of my opinion (WITHOUT SPOILERS) in order to help you decide wether you should or NOT watch the movie.
Plot: Basically, this movie has a very basic story line, it's not complicated, but it's not that original either. Although you shouldn't expect much from a kids movie, I still expected a bit more from Disney.
Characters: We still see the same characters as in the first movie, they are still lovable and all of them have a great arc. However, I would have liked if they had introduced more compelling characters to the universe.
Visuals: Great visuals, awesome renders, animation is practically flawless and is full of life. Everything was well designed and looked lovely, just like in the first movie
Appeal: The movie is very humorous, practically every joke landed in the theatre I saw the movie in. Jokes are very lighthearted and there are scenes that had me rolling
All in all, a decent movie. But for an animated Disney movie ? It doesn't rank high in my list.
