I have several of them now (7-10-ish?) and the ones i have I quite like. I certainly agree there are some that are off-putting for one reason or another. I haven't gotten into the Bishoujo line yet, but I recently saw three of them in person, and I like them. I'd like to get some of them now, but in general I feel they're more sexualized for no reason than the Ame-Comi, so they'll probably be harder to sell to my wife.
Speaking of off-putting, Have you always talked in the third person, and I just haven't noticed until now?
