I have not seen Bidaai, so it is difficult to compare with that.
Yes they have selected nice actors as cast in PS.
Prabhu has improved a lot compared to his initial scenes in emoting his expression.
Karthick still does not have much strong role yet. So difficult to analyze him.
Revathy is good. Has great improvement.
Jothi needs more scene space to showcase her talent I guess. May be more Kathick/Jothi scenes coming.
Love Abhi and her husband acting too! Nice job director!
