In MY opinion: Annoying voice, annoying personality, and boring music. No artistic growth or change whatsoever, unless you consider this album "mature."
Because she's talented and has good music.
She has an opinion even though she knows people will disagree on it she says it anyway.
She admits her wrongs, like when she said that she was a bully and when she admitted that she claimed she was using drugs during her sober is sexy era.
Because outside of this messy Stan world the gp respects her for what she's doing for mental health awareness.
