The show might not have the same impact as many K-POP survival shows because there is a paywall for the full version and very disorganized.

You need to pay to watch full version with behind the scenes and pay for voting (in which I think is not fair). The production companies does upload few behind the scenes clips here and there on their YouTube channels, which is nice but there are no subtitles, therefore a lot of international viewers will lose interest. (keep in mind they have 4 different YouTube channels)

The voting is not in real time, everything I watched from ep 1 to ep 10 have been prerecorded.
On episode 10 (after round 2 performance), they announced the top 30 but then on episode 11 & 12, all 63 trainees will be performing for round 3, voting still going on for all 63 in their app, but top 30 have been announced and 33 got eliminated (They mentioned in their voting rule there will be no elimination in round 1 and 2.)

It's very confusing on how they picked the top 30.
The show is very disorganized, the above descriptions proofs that how confusing and disorganized they are.

I would have given higher stars, but unfortunately the show is very confusing and requires you to pay to watch full contents and vote for I don't even know what. If I didn't love watching these type of survival shows, I think I would have given them 5 stars (the 5 stars are only for the hardworking trainees.)

Also I didn't like the fact that an entire debuted group joined the competition, they already have a fanbase of their own and there are 6 of them, tbh, I think they lacked on many things, but they always get to top 15, I think is not fair for other more talented trainees in the program who came in as solo with no fanbase.

Note:
The description above says total of 9 episodes, right now I am on episode 10, and round 3 performance will be on the next 2 episodes, then they will pick top 18, after that the finals will be on March, therefore there will be more than 9 episodes.
