Someone needs to tell the Love Live choreographer what symmetry is.
Unless like...there is an in world justification that the members of μ's are just terrible dancers. The actual 2D animation flourishes that focus on one character where they do a unique nonsensical spasm are bad enough, but why are CG characters preforming an identical move so out of sync?
At one point they use a single snowflake falling in front of the camera to provide a character wipe when they go from 2D to CG. It's pretty hilarious.
