What I liked:
1) Performances
2) Letters to the contestants from parents
3) The politeness and supportiveness of the contestants
4) The audience and their support of the contestants

What I didn't like:
1) Editing was REALLY bad. Repeated takes to see reactions of judges and other contestants so content is interrupted/missed. Also, things were shown out of order. They would be getting ready to show a performance, then they would throw in a competition they did outside during the day.
2) Camera work - every time they showed the entire group it was blurry
3) The purpose of the multiple star master hosts?
4) Extremely confusing voting.
5) Not putting the contestant's names, just using their current ranking number. There were so many of them that looked alike, I would have liked to have names go with the faces.
6) The elimination process. It took a whole episode for each elimination. It took forever for them to name the contestants that were going to continue on. It didn't build suspense; it was just irritating. Then to show three candidates at one time, when only one was continuing on in the competition.
7) For the second elimination, putting everyone on a team, having them do the work and eliminating half of them. The groups then had to reconfigure their groups and their dances, then got called out by the judges for not being prepared.
8) When the winners were thanking their agencies, that surprised me, which sent me to do some research. All of these guys have been trainees for up to three years!
