There is nothing wrong with it, BUT BB wants you to think there is. They don't want cool and calm people on their show.
Guys its been 10 seasons, you should have figured out the formula by now:
1) Person X turns out to be cool, calm, calculated.
2) BB tells Salman to critising person X for lack of entertainment (but what they really mean is "please...please fight!"
3) Unfortunately for BB person X will actually be liked in the house and not be nominated. If they are nominated, then they will be saved by fans.
4) BB brings in guests and ex-contestants to tell person X that they are boring once again
5) Either person X now gives in and becomes a clown OR they remain themselves until the end.
