Overall, this movie was good. Yes, it isn't as good as the first movie but it's still good in it's own way. Moana looks great in this movie. Here are my complaints.
There are a lot of new characters which are uneccesary and they didn't get enough screentime. The pacing felt a little fast at times, and the movie felt like it went by quick despite being 1 hour 40 minutes long. There weren't any big villians in this movie but they set it up so that the next movie might have one. I disliked how they made Moni a Maui fanboy. I also dislike how there were kids who were "admirers" who look up and try to act like to Moana and Maui. They were uneccesary and cringe. Also, we really don't need any more new characters! Keep the OG feel!
Moana 1 had everything perfect. The pacing, the right amount of characters and their appropriate screentime, perfect villians. The first movie is just iconic and not much can live up to the greatness of that movie. If the first movie is a 10/10 I would rate this movie a 7/10. I still liked it for the most part.
There is room for improvement and I hope they take their time with the story Moana 3.
