I think a lot of her overseas PVs tend to be disliked because they're on location. If you think about it, her PVs shot in LA or New York are rarely ever done in a studio, which people seem to prefer from Ayu. Though if the PVs ended up like Dearest (California, don't remember where) or RAINBOW (Japan) I don't think people would mind.
