ZNMD opened better, its not a negative point to be taken. A₹90cr for purely plex release in 2011 was brilliant as it was more than Bodyguard, RAONE, Ready that year. In fact, back then it was only less than 3 Idiots in plexes. So it not only opened well and trended better.
S30 on other hand had poor opening and picked up basically on Saturday to decent numbers.
Two are different; ZNMD opened with superstar reach and did high level numbers; S30 opened poor, has much bigger ground to cover, which it slightly did and reached okayish 140cr approx. There is nothing great in number or trending here.
