I think American Idol should keep her for next season. She is talented and has a lot of experience. Her advice is usually good and it is better than what Paula says.
That said, I think it's better with 3 judges, 4 is too many. If they are going to replace Cara, I think they should replace her with guest judges each week. They did that a while ago and it was interesing to see different artists offering their critiques.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
