So as far as the 3:3:3 challenge… I think that the songs were all developed differently. School life, I think, had all of 3racha and Woojin and I.N composing and producing it, while 4419 was just Bangchan, Seungmin and Hyunjin and Glow was just Changbin, Felix and Lee know.
I don’t think that playing it fairly safe was a bad move for Bangchan’s group. They wrote a song that allowed Hyunjin to focus on the aspect JYP said was lacking and delivered a solid performance.
But just remember, Lee know had been a trainee at JYP for a mere few weeks before the show started, and it shows.
My only somewhat spoiler is that… it might get worse emotionally before it gets better.
