the main reason is karunya knows he is good.. this is not at all appealing.. may be amey also knew he is good buthe wud always eagerly wait for the judges verdict.. if that was pretence then he really did a good job..
but karunya comes across as a person who knows he is extremely talented.. so may be the public feels that someone else needs our support.. someone else doesnt believe in himself and our votes will show that he is good..
i guess the same thing happened with rahul vaidya.. he was technically the best but still was out in top 3.. the reason.. he knew he was good..
its like a perfect painting.. if it just tooo good.. its not that appealing anymore..
