Ok, maybe I wasn't clear in my findings... I don't think the judges changed at all since the first season, only what the director decided to air. Remember, the viewer only sees and hears what they decide you'll see and hear. If they had aired the garbage at the first (on the show itself, because it was available obscurely) it might not have been so "acceptable."
I'm sorry that you seem to feel let down by the show. It can be disheartening to put your time and energy into something, and allow yourself to enjoy something and then, because of standards feel like it's been taken away.
Maybe there's a new show coming on that will fill the void.
