I'm an opinionated sod, and since I'm addicted to the song and want to learn the dance, I've watched the pV way too much and have come to the following conlcusions in my own biased opinion.
The set is absolutely gorgeous! <3333 It's the best set in a PV since god knows how long, possibly Irropoi Jirittai. I don't know. I love the floor and ceiling, and all the gold in the close ups. It looks really nice. Five stars!
The hair styles are brilliant again, minus the feathers. Eri's long hair grew on my in this PV, it looks really nice, thank god, since Eri always seems to get the less impressive hair cuts some how. And this may seem really odd, but the earrings! OMG! *__* I want them all!! The costumes themselves are ghastly though. x_x I hate the feathers, they are horrible, it reminds me of CanCan dancers, and MoMusu are infinately more talented and too pretty to be associated with such people X__x;
The dance is great, I can see people in dance classes in Japan learning it, which means more publicity regarding teens and children and what not
However, Koharu should not be the lead, firstly as there are more talented dancers than her in MoMusu. Sayu is a very good dancer and since she didn't have much too do, she should have been more central I think. She needs a centre dance part, it makes up for her lack of singing skill. Koharu's too CHEERFUL! In cuter, happy songs she's perfect but throughout this she pouted or smiled - or looked like she was trying not to smile. It drove me crazy >__< I hope to god in live performances she isn't going smile all the time because it doesn't fit.
Junjun and Linlin rawked. They really did. I think they are going to fit in very well. <333
