It does seem Mad World could of been more. But the view of the PV usually comes from the director not ayu. Ayu will just approve it. It could just be ayu has too many yes man in her team, meaning people are to scared to say no to her. I think a fresh team could do wonders, but at the same time, ayu's PV's don't really compare to other artist who seem to put a lot more into the PV. If anything I would say budget was a thing, but that's probably because avex spends more when they expect a higher return, and this album has already essentially been released / leaked.
Ayu should travel for a little for music inspiration, and let her journey paint the PV's
, instead of these, what seem pretty average to what she has done in the past
Though ayu usually does a happy and sad PV, these both seem like sad PV's. I cant wait to see the rest
