I wanted to read what other posters here think without getting too off-topic on the other thread. And here's what I think :
Their PVs are somewhat minimalist in the sense that they mostly show the girls playing against some cute backdrop. I can't say if it's a good thing or not, but I don't dislike it. In fact, I think most music videos from other groups are similar. Do I think it's doing a disservice to the band ? No. I don't think a band's success hinges on the extravagance of their music videos. In fact, music videos are more of a side-line. You see them a few times on TV, maybe, but it's the music that sells.
Alrick also says that those PVs do not satisfy hardcore fans. I don't think most companies care about hard core fans, but more about casual fans, and the new ones they can "convert". Trying to satisfy hardcode fans is usually an exercise in failure.
Mikan argues in that same thread that the videos don't do justice to SCANDAL. Considering how beautiful they look in them, and how much SCANDAL is banking on the fact that all four girls are very attractive, I think that isn't a very fair thing to say.
