Come'on guys, we are PaRud fans and it's absolutely not right to compare rudra with varun and paro with laila !
On paro's expressions, I must say the biggest reason would be sanaya's absence and scenes with BD obviously won't create such impact as a real actor would. I remember, in MJHT, when samrat had an accident, the forum was filled with topics showing disappointment for Gunjan as she failed to show an expression of worry/anxiety, and in that scene too, sanaya's BD was used so obviously, no such expressive scene that was...
So, please, be patient and avoid making posts saying that 'Paro doesn't love Rudra'...for once remember the 'standing-on-one-leg-in-rain' scene, then she was blamed by Rudra and now by the forum-wasis.
PLUS, we are yet to see how she finally gets rudra back recovered, don't forget the numerous articles on that part !
