I loved the premise of this survival show with the objective to found a vocal boy group of only 4 members. It felt fresh and original as a concept. Unfortunately, it fell a bit short concept-wise: it almost looked that mid-way the producers changed their mind on the initial idea. They lost their concept on the way, with no real differentiation compared to other singing competition that I have seen. The way they organised and splitted the episodes / missions felt also quite strange, as well as the voting rules and principles. The episodes were quite short for such kind of program but I felt they could have spend a bit more time in building stories around the candidates. Indeed, maybe the episodes were too short to fully get attached to the more subdue candidates...

While it felt short in story-telling and production, I must say that I found the cast quite good overall. No obvious bad / fillers singers, just talented individuals with of course some being shown more than others. Nothing outrageous, except maybe for some missions where I think they could have shown all performances rather than scratch off some with just a better editing and split of content between episodes.

Regarding the cast, I was truly happy to find back some very familiar faces met in others tv shows (such as Geonu, Jay, Lee Hwan Hee and Wumuti) and I felt I really made some interesting discoveries among individuals I did not know before (e.g. to name a few: Kim Min Seo, Choi Su Hwan, Jeon Woong (from AB6IX), Lee Kwang Suk, Park Je Up, Kim Seung Hun (from CIX), Seon You (from UP10TION), Bain (from Just B which is a group I like but did not know a lot about the members -except for Geonu), Bitsaeon (from M.O.N.T), Kim Seo Hyung, Jung Soo Min, Kang Ha Yoon, Park Joo Hee, Choi Haram and so much more...). I liked as well the MC and judges casting...I knew most of them, but again, episodes felt short to get attached to the ones I did not know from before.

In terms of rewatch value, I know that there are some performances that I will gladly rewatch (and already do) in the future...I will for sure rewatch again Dangerously, River, Bad News as well as honestly every interactions of Milky-up who were just so lovable and wholesome...Overall, I am happy with the results of the finale. The winning team was my favorite but honestly all the candidates were so good that there were no "bad" choice. However, I was disappointed by the finale production, it lacked strongly in entertainment value and felt draggy as well as super expected. The best performances of the show are all coming from the first third / half of the contest...It is a bit of a shame that the orginal songs did not grab as much my attention.

I would recommend this to people that are looking for a survival show with some great singers and performances. It is pretty entertaining with a good cast and the concept of forming a vocal group is quite fresh. It lost some steam along the way and production could have done a better job to spread out content and to make the finale more exciting.
