It is very entertaining and not too cruel even if it is an idol survival competition.
There are a lot of different contestants with each their own personality and they all have strong and weak points. It is very authentic it does not feel like watching a fake show.
The concept of team is also interesting to watch with the different planets because every group has its very own color and vibe to it.
Every episode is very meaningful and not just a bunch of fill-in episodes to the final reveal
The judges are wholesome too and they really add to the fun of the show.
The editing is not evil which is a huge plus of this show.
