I haven't seen either one of them, so I cannot comment on that. But yes, her character arc is interesting. She also writes articles about the nature of art, humanity etc. that sometimes come off as rather ranty and obscurantist. Like someone operating within her own personal frame of reference, if you know what I mean.
From what I've understood she used to suffer from depression (or some other similar mental health problem), and I've no doubt that the art she is creating now is helping her deal with it better than standard schlager/pop.
She used to be married to the drummer of super-popular pop-punk band Apulanta, and they spent ages (more than 5 years I believe) getting permits etc to built some fancy eco-mansion in my dad's hometown of Heinola. They became a bit of a local laughing stock because of it, and by the time the house was finished, they had already broken up.
