this story is about children overcoming abuse from their father. I know a lot of people loved it so much, but I didn't (not as much). why?

1st: 12 episodes seems to be a few, but the duration is 1:20 hour. that means the show has 14 episodes lasting 1h. it's not so far from the usual 16;
2nd: there is a lot of things happening during these 12 episodes: a music star being born, an old music star surviving the decline of her career, 2 families getting rid of their abusive father (this alone should have been enough), and how a young girl got lost on a remote island and how she got rescued, and how she adapted again in the society (this also alone should have been enough). the result is a little bit overwhelming. I really think that the quality of the show would have been better if they chose to focus on less main subjects.
3rd: the music was nice, but I didn't LOVE any of them.

what I loved: the actors were really good, especially the young actors. the atmosphere of the show was very well transmitted. the writer did a very good job sharing his views about the complexities of relationships. you are sometimes very mad at some characters then understand that they had their own reasons and it's forgivable. I think that it can be very interesting to re-watch the show.

audience: not under 15 because there is some violence
when to watch: it's a dense story, watch it on week-end so you'll have some time process it.
even if it's mostly cheerful I didn't find it relaxing.
