I liked the PV and I am impressed with how photogenic all of the 9th and 10th are. Quite honestly, I think the child like nature of the song was a refreshing change of pace in the 'Idol Genre' of music, and they might as well take advantage of the young age now to do a PV like this.In a couple of years there will be a flock of very pretty mid and late teen age girls who will be able to handle the angst filled teen drama pop, or the hip hop influeced dance songs, so let's enjoy their 'baby Musume' stage now, because it won't last for long.
