mrs balla and mrs IyerExagerated

I love this show and the couple is outstanding ...I really love ishita...but I just feel Mrs Iyer's way of talking must be improved ... ...I like her character but as a Malayali(neighbours to tamil nadu) I think this Tamil lady's character is a bit exaggerated... especially the way she speaks...too much a dragging ...I know people speak another language with a different accent but this is not portrayed properly..
I don't know about Punjabis ...but I em sure mrs Ballas Character is also a bit exaggerated version of a punjabi lady
