I agree with you. The fun of the show is to watch the growth of those who have the most potential to develop their talent through this experience, and appreciate the opportunity.
That's what I like about Will. (and a few others to some degree). I just wonder if he would've been more ready for the experience in a few more years.
Will is cute (although I hate his hairstyle), and he has a pleasant voice. However, we in the viewing audience can only judge based on what we see coming across our TV screens. To me, Will appears not to be taking this competition very seriously. He has a lackadaisical, almost disconnected stage presence, and he's picked fairly easy songs.
Is this due to his age? Maybe, but I don't think so.
