About the dancing in my opinion:
- ayu and the dancers did a great job on this PV.
- The dance DID fit this PV and even helped the concept.
- No I don't think it lacks the plot, I know why ayu and the director left the PV like this.
(doubt ayu would ruin for herself) the dance showed the rage and war-like feeling ayu wanted to put into this PV so it had the dance side and the plot side with the kids, which is awesome.
- The moves did fit to the song.
Otherwise people really exaggerate about the dancings and take it too seriously =P
