Appu's character is negative for me, not gray. I could have easily accepted a gray heroine but between Appu's expression (actress's fault) and her haste of killing Malay's mama, the CVs moved her from an innocent person to a killer in a matter of 3 episodes. I wish they had spent more time on the character - explained more her thought process and reasoning. Just one incident - family's insult turned the character around completely -- was hard to digest for me. A slower and more reasoned transition would have been perfect. Right now, it often feels like she is dying to use her vishkanya powers to get the world to bow to her.
I do not like how Veda's character has evolved and her obsession for Malay. Veda is so blinded by Malay that she is not seeing anything else or how her action can harm someone else. What if Appu was really innocent?
