Must have if you like BTS, if you are Suga solo stan or if you like documentaries about musicians.
I have watched it - and rated so high, usually I rate this type of productions 6/10 - bacause Suga is my ult bias in BTS and one of my favourite soloist.
This movie shows how hard creating music can be, that it is not the easiest path in the world and there are always some struggles - even if there is also a lot of happiness.
