Everyone Is Jesus in Purgatory: Interpretations of lyrics can be surprisingly variable, both in Japanese and when translated. Some sections of fandom seem to like to downplay the suggestive content, while others seem to be able to find it in everything. The truth is, as usual, probably somewhere in between.
More like Yutaka who, seeing that he is one of the co-founders of the band (along with Imai.)
Memetic Sex God: Atsushi. I don't even think this is a controversial opinion, or even slightly disputed.
They Changed It, Now It Sucks: Averted. Apart from a minor fuss back in the days of "Taboo", when the band first acknowledged their darker musical roots, BUCK-TICK's fanbase seem positively welcoming of the continued Genre Shift that characterises their work. So what if you don't like their current direction? There'll probably be a new one next time, and everyone seems to have a different favourite. ...Though Sakurai's attempt at facial hair didn't go over quite so well.
WTH Costuming Department: Usually directed at Imai, though Sakurai is not immune to this (wedding cake-ish coats and beige pleather manskirts spring to mind), and most of the rest of the band have also had moments in the WTH spotlight.
