the problem is that the group is not as it once was.
the fanbase is different. (worse)
the members are different. (worse too. ok, this can be very subjective and personal, but although Tenten is such a fascinating girl, I think that the members gone brought more to the table)
the music is different. (the only point I think that hadn`t decrease. they continue making very good songs, imo. but I`m biased to begin with, since I`ve been a pop-punk fan for longer than an idol fan)
and last but not the least, their "essence" (or should I call purpose) is different. the group was created to be a provocative idol group that pushes further than others ("others" aka Passpo, as once Pour Lui said in an interview that was one of her inspirations). now I just can`t see an idol group anymore, to begin with. they turned into a borderline idol act (like hy4_4yh), that uses some idol antics but is not part of the sub-culture. (I think this part of my post will turn very tricky... maybe it`s understandable. trying to make this concept a little more visible, just look at how they nowadays make more shows along rock groups than idol stunts)
