I don't think it's a low budget drama, that's just the standard style of Mehree Jabbar who I am sure can find tons and tons of producers to finance even the most lavish plays for her. Infact this is Humayun and Abdullah's production so I am sure they would spend lots if it was required and that's the beauty of this drama that despite of being a mega project, the simplicity is there in every aspect of it.
I didn't mean low budget as an insult. I just meant that Doraha is good not because of the amount of money spent on it, but because of the simplicity and good acting.
