I really wouldn't have minded if Karin had about the same amount of solo shots as Riho/Mizuki honestly. About twice as much, though, is overkill for any girl (I believe mutterings would have been made no matter what girl it was... unless a back girl). I love the Yuugure PV so much, but I have to admit I'm thrown out of the PV when there's long shots of Karin. I'm like: huh? Then it makes me think of how MM must of thought when they saw the video the first time. I get afraid of things like resentment being created between them... of Karin feeling bad, herself (it's got to be an awkward position to be put in, I know I'd feel very awkward. Kanon's apology makes it seem like SHE feels awkward about the whole situation now as well) Then other things like the fact that this new line-up isn't well known enough to be throwing other group members with such a big presence... I would have loved it if the title could have been the PV ft. Karin edit to make that clear...
I think there is a lot of huge reactions being made (some a bit extreme and constant which is probably not needed but people can get really passionate about things), but I don't think anyone's wrong for being upset, especially since most of it is behalf of the girls rather than because anyone dislikes Karin. Be what it may, but Idol fans get very attached to these girls, they want them to succeed and they get protective of them even if it's silly for them to be acting that way.
I have a tiny hope they'll put a Kanon version on youtube eventually, but I do know realistically, being a back girl, they probably won't go to the trouble they went with for Karin, since I think it's quite obvious now management love Karin A LOT for good or for bad. Maybe this was their own way of combating J=J not doing as well or not getting as much focus? (though if they had added Karin from J=J somewhere on the video that would have worked a ton more. I mean how is anyone going to look up who's in the video if they have no idea who she is. They'll just look up Morning Musume, get confused when they don't see her and if they're casual listeners/watchers just give up there)
On a lighter, more amusing note. I completely understand and appreciate the hairstyle rule that MM has now after this
I kept mistaking Duu and Karin for each other in the Dance Shots of both PVs.
