^ agree totally. I think that's been the key to a lot that's been said. Berryz doesn't
look great, but fans are kind of used to it. C-ute looks great and a casual observer would be able to agree. I don't actually watch C-ute stuff too much, but I can see why people do.
In terms of facial expressions, Maasa, Yurina, and Chinami are all missing something. I honestly find it weird that at least they haven't managed to fix it for PV filming (when you can be critiqued by the director), but I'll live because all I really care about is looking at Risako

To be real though, as someone that has danced and performed for things on stage, facial expressions are always always always a big deal. I've spent lots of time working on how to look cool, hopeful, or whatever--it's not easy, but it is something you can totally work on if you have a mirror and a little time. So I'm not sure how they've escaped from getting better. Maybe management or whoever thought they looked fine enough. Whatever, I'm not in charge~ I still enjoy Berryz a lot. I wish they would do better, but what can you do.
Personally, I would like Berryz to do another cool, rock-ish pop song like Otakebi. And at least give them matching outfits and a normal looking dance, I mean, come on. I don't get why the outfits and dance are so terrible recently.
