I have always felt that the judges gave out 9s and 10s more easily than they should. They shouldn't have given out as many 30s as they did.
Think about it, 30 is perfect. So a performance getting 30 should be perfect and flawless in every way. Now, I'm not saying there haven't been flawless performances. There have been, absolutely. But not as many as the number of 30s given so far.
Getting 30 should be harder than it has been so far in this season. Contestants and choreographers should produce their absolute best work in order to strive for and to achieve a 30.
So I'm glad with how the judges criticized and scored everyone in today's episode. Yes, it may seem a little strict all of a sudden. But I am happy with them taking this step, especially now that I think we are at a stage where all contestants have a lot of potential. There isn't anyone particularly weak.
