Compared to the other shows on Nick Jr, Rainbow Rangers really has poorly done animation for the characters. The voice acting is really hit or miss, it either doesn’t fit the character at all, is hard to listen to, or is one of like 2-3 characters. For some reason the hair in this show is done in a way that is strange to me, Floof and the goddess lady being a prime example of how it looks more like chunks of clay than hair. This show would have done better 2D than try to compete with the other better made CG.
And like everyone else said, the song literally takes up a huge portion of the episode. Its far too repetitive and time consuming, especially with how it introduces girls who won’t appear in the rest of the episode.
