Curtain Call for American Idol?

First Simon, then Ellen, and now Kara.  First, I've never watched American Idol.  I basically hate Karaoke and AI is nothing more than a televised Karaoke event to me.  I have no idea who Kara is or what she has done in her pre-Idol life.  With 3 of the 4 judges gone, isn't it time to put this thing to rest?  It won't affect anything I do, but it sure will clear up my Facebook news feed on nights that AI airs.
