People were like: the show flopped because nobody wants to see has-beens perform.
Wrong, peaktime has been very successful. Just as successful if not more successful than Boys Planet right now and has put a spotlight on the boy group Vanner.
The Unit failed because 1/4 of the contestants just debuted that year and were rookies which goes against the premise. And by doing a girl competition and boy competition at the same time without ANY interaction between them was stupid. Either do co-ed challenges or spend the season on one gender. Finally since Mix Nine was airing at the same time, neither show was able to succeed.
