Nearly perfect
It really is one of the greatest songs in the world. Noone will ever doubt this.
The animation was great, it really fit to every part of the song. Great job!
But here comes the but: The proportions of the people looked awful, even for comic style. Some other things weren't perfect as well, like for example that Aaron Carter had no elbows when he punched Shaq in the face. Some things just looked odd.
Anyway, I still enjoyed every part of it and think that it's already a cult movie, so i can't give you less that 10 of 10 points. Keep making such great stuff!
