The typical idol showcase. It's tough to get it to work properly with a large group because they often forget to account for all the group members to bounce off each other, let alone give each member a moment to shine individually, as the focus keeps shifting awkwardly without clear balance.

Contrary to the synopsis, they barely helped a couple of people very loosely while spending the remainder wander around menacingly. They wanted to give the other sisters some screen-time and story but there was simply no available for that. The whole thing with the noisy male was done very poorly.
