Shakti's performance is great and I had no doubts his performance would be anything but when I got to know he will be joining the show.
That being said, given the supposed big betrayal karan thinks he has received from the two people he loves the most, I'm not really seeing much emotions in him when he speaks about preeta-rishabh or during all those scenes he was watching rishabh and then kavya and preeta.
There's no pain in his eyes or voice or tears for preeta-rishabh's betrayal like the way karan before leap showed during the party and after the party before he fell to his death. The emotional quotient is missing from shakti's performance as karan where it is needed to be shown in scenes or moments where he thinks about the betrayal or when he sees kavya with preeta and rishabh.
All we get to see is hate, anger and attitude from shakti's karan. I hope the writers going forward to pay attention to this that karan should be showing just as much pain as he should be showing anger due to feeling betrayed by the two people he loves.
This purely angry and arrogant karan throughout just isn't cutting it, and I felt this way since the moment they showed his memory back.
