The only thing I would have against MM is that they kind of exaggerate the whole cuteness thing, which I kinda have come to hate
I guess you get used to it, but then you see all these people in the US and they just totally think that everything in Japan is like Harajuku Lovers brand clothing...it just gets annoying.
About the whole "lolita complex" mentioned above...it is really kinda disgusting, but, it's not gonna change...so...just have to live with it I guess.
