C'mon. They are new and you cannot expect everyone to be a natural and spontaneous.It takes time to get accustomed to and in tune with the grrove of a character. Look at Prerna in earliest episodes of KZK or even Smriti of KSKBTand even Eijaz's acting has become good only after KDMH.Not everyone can be spontaneous and natural...it takes time for some ppl.
As for Neha, I don' see anything wrong with her rendition of Kripa's character. Kripa is a soft, sensitive and kiddish youngster and infact, i think she brings out the vulnerability of Kripa very well.
As for Angad, even if he doesn't turn out to be much of an actor, his brooding expressions and intense characterization can help because Angad is about fiery fury and internal conflicts.Iqbal has been able to get into Angad's external persona, let's see how he brings out the character.
So, let's take some time before we judge them.
DOMINUS VOBISCUM SPIRITUO TUO.
Take care,
GOD BLESS EVERYONE,
