Humor Is King
What the contestants and judges show is that you are allowed to have preferences. However, the over arching goal is to be humorous. In fact the judge Catalin Bordea is quoted “I took on all the numbers that are only headed for him (Bendac). If you don’t play this, it makes it awkward.”
If a performance is too serious or is simply a titillating performance it does not work well for anyone. The goal of the show is laughter and not just to titillate. Therefore it is important to balance what the surface provides and if the content is funny.
This makes for more genuine acts and something that people can relate to.
Cheloo does end up voting against the act. His comment that the person is not sexy is not only to make the other contestants angry, it is to be genuine to his own taste. This allows him to have a real review. There is no point in a show where everyone is going to say yes and have no genuine feedback.
