Jessica just didn't have "it". She didn't capture the peoples 'hearts' (much like Anwar and Nikko). Weight had nothing to do with it. I think Scott should have been dropped after that dismal display.
It is interesting to note which songs the contestents are "allowed" to sing... I like the "hard rock" stuff and don't think I have heard any decent hard rock songs on the show.
How about have a true "idol" show where the song lists are more open.... Wouldn't you find it interesting to see the singers do some of the older rock stuff.... How about some Zep?
