Disclaimer - 6/10 is the way I usually rate this type of production, so not bad rating.
It is really good documentary to see more of the boys, get to know them even better. Also it was good too release it cause it made it clear that boys also need to do they solo projects to grow as the artist, they work perfect as a group but they still are 7 individuals and need to have something only for them.
Well if you are army you just have to watch it.
