It was a nice, short survival show with good intentions (except for making money of course).

The Story aka The Show's Concept

I always enjoyed the survival shows that focus on less popular idols, because there is truly no disadvantage for said idols. Their debut does not depend on the show. They can only gain popularity, so the risks are truly minimal (except for emotional distress, but then they will be in the same emotional state if they won't gain the fans anyway...). I don't believe the voting was fair, but I also don't believe it's possible to make it fair, so it never bothers me in shows like that. It makes the watch less stressful and I can truly focus on enjoying the performances

The Acting/Cast aka The Contestants

I enjoyed all the groups. Before the show I was already a fan of Oneus and Pentagon, but seeing how fun the rest of the boys were, it did make me want to check them out too. The best part of the whole show were the interactions between teams and how they were hyping and supporting each other. Sadly, we barely saw it in the last episode, and with that I must say the finale was a let down. While the performances were amazing, I wished to see some reactions from other teams and listen to more of their opinions. Can we also appreciate how crazy witty Jang Jun from Golden Child is? The phone call in episode 1 was one of the most entertaining things I have seen in the past few months.

The Music aka The Performances

I cried. Twice. If anyone likes to be an emotional mess I would recommend watching Pentagon's Shine + Spring Snow performance and The Boyz/Oneus' Heroine one (which also shows how close and supportive the boys are). Other stages that amazed me were: Oneus' Warrior's Descendant and Lit, ONF's It's Raining, The Boyz's Sword of Victory.
The teams that impressed me were Oneus with their storytelling and messages, Pentagon and ONF with the music arrangements and The Boyz with innovative ideas and stunts.

Overall, I think it's a good show that does a great job actually presenting the groups and their strong points both in terms of music, but also their unique personality.
