My first reaction was that the choreography was kind of off-the-wall, with so many strange, jerky, and ungraceful-looking movements (at one point early on, all I could think of was a sea anemone

). But they do an excellent job with it, and the overall effect is so striking that it works -- it's
not just another generic idol dance. I think it will get people's attention, and it definitely sets them apart from other incarnations of MoMusu. I like the overall effect.
Ther's something about the background CGI that reminds me soooo much of old Wink PVs

-- but that kind of works, for the same reasons that it worked for Wink: it's part of what they
are now, in a "take it or leave it but you're going to have to deal with it" kind of way.
And the overall effect is something that AKB just couldn't do at all, which is important -- it draws a major line between what MoMusu is and what AKB is.
If madness made us strong, we would all be invincible.
