He isnt harsh.... he is being honest... he is much better than Alisha, who on day one says "you are a show stopper" and "What a performance" blah blah blah and then on day two says "the janta protected you, despite yesterdays performance being not so good"
If she were indeed supportive of him, she would stick to her guns and words.... not go ping pong on them like this. She is actually disturbing the morale of the singer.... putting him on a high on one day and then pulling him down the other day...
