American Idol has to be the biggest scam going, Personally (I know, I never have anything nice to say) but I think the winner is determined after the auditions. The main reason I watched it before was primarily for the auditions, they are extremely hilarious, and it only becomes funnier when you get the "sobers" entering and crying when they don't go through to the next round. Heck, they come in and sing like Celine Dion and wonder why the following comment is either "you'd make a good karaoke singer" or "you remind me of one of those singers in a mexican bar". I'm not an avid fan of the show but it really angered me when Carrie Underwood and bo Bice made it to the final and it was clear to me who was the best singer and Carrie Underwood sang like crap. I think that was the turning point for me when shows such as these can't be taken seriously and at the same time exploit the contestants who have made it to the latter stages of the contest.
Of course it's not all bad, Simon does his little bit to spice the show up which would otherwise be a total waste of time without his presence.
One thing I'd like to see more is simon being more brutal, IMO I think he has softened a little as the series have passed. More brutality I think and less singing.
