Brother Bear 2 is one of those completely un-needed sequels and this is one of the worst Disney sequels in my eyes. As I find the first Brother Bear very entertaining, the sequel was just a dull love story. It was more goofy and all the scenes that supposed to be serious and exciting, weren't that exciting at all. More like "Rescue my Damsell-in-distress and we'll fall in love". Sequel do not bring anything new and the characters are completely unoriginal. Just take a look at Anda and Kata, the moosettes who are nothing more than just genderbent Rutt and Tuke!
All actions lead characters to fall in love, because this movie was made only for main characters to find love interests. It takes away from their well-developed personalities from the first movie, not to mention a lot of plot holes. Brother Bear definitely lost it's magic in case of this.
For me Brother Bear and all it's characters would be perfectly fine without this sequel.
