I started watching this not for the contestants but for the Judges. Most of the judges are from YG.I love YG Judges cause they're cool and I loved Treasure box and Babymonster evaluation.
Pros ---
1) of course the judges .
2) we get the singing and rapping evaluation too which was absent in I-land .
3) the judges chose the top 12/16 so , trainees didn't get to choose the popular ones over the skilled ones .
4) the voting was about whom you wants as teammates which was who you wants to eliminate in I-land .
5) high production and eye candies.....

Now I will talk about the cons ----
1)when you get skilled judges you expect to see highly skilled trainees too . But was there highly skilled trainees?
Remember they're here in survival show not auditioning so , of course I I will expect some cut-throat compitition.
2) lack of attachment.... don't get me wrong but the unfair judgement in I-land made me attached to the ground. Specially when there were equal number of skilled trainees in Ground and they were desperate...... remember the fire performance? Even the judges were shocked and nearly 6 trainees got eliminated in first round....
But in I land 2 the I-land team is better and the ground trainees looks meh in front of them....
3) Determination ?
If you watched treasure box ,baemon evaluation and even in I land you'll notice the burning Passion in their eyes ....but here more than half trainees are passive....
Final say ...
I won't say this is the worst survival show....cause the production, growth of the trainees and judges are really good and of course good luck to the new group ....
