rajiv was trying to incorporate dance and comedy and he had fun and entertained the judges...they even said he was hilarious, although he was out of sync.
manish concentrated on comedy rather than dance, which he has apparently done before, and the judges didn;t find him as entertaining.
archana admitted to doing a half-assed job, and acted like she knew it wasn't gonna be a good performance...everyone expected her to do better, and by admitting it before the judges panel, it looked as though she was taking her winning streak for granted, and not performing her heart out everytime. If her poor, ailing hubby could kill himself on stage, she should have tried a little harder...but she was tired...
