This, quite frankly, is a very poor imitation of American Idol. People seem to liken this show to American Idol, but in reality, this is a completely scripted show with poor judging and a formulaic format. Every bit of this show is rehearsed...the script is completely written and I'm almost inclined to believe that the contestant is in on the script. If you're expecting a show like American Idol, don't bother viewing this.
As for the actual appropriateness, this show is not any worse than any other competitive show (mild language with censoring, some sexually provocative clothing choices and dances)
