Is It Mandatory NTR to Respond on Biopic?

Though a couple of cine celebs responded positively post the release of Ntr Kathanayakudu, Young Tiger Ntr has kept a stoic silence which made movie buffs nonplussed while Natasimham Nandamuri Balakrishna's fans are reportedly trolling Young Tiger more than like anything. 

The trolls against Ntr have been intensified post the Young Tiger paid homage to his late grandfather Ntr on the latter's death anniversary. 

Balakrishna's fans questioned him why was he showing false respect on late Ntr without promoting the biopic.

But then, why hasn't Ntr responded on Ntr Kathanayakudu? There maybe several factors associated with his gesture. Ntr might have felt it was a substandard film and his babai was not suited for the role of his grandfather. There could easily be another reason. Though Balakrishna graced Aravinda Samtha event as a chief guest and Ntr attended Ntr biopic's event, there mightn't have really good terms between Ntr and Balakrishna. 

Balakrishna's fans should have understood these reasons. Instead, they unnecessarily compelled Ntr to react on the film. They must make out the fact that it's not mandatory Ntr to respond on the film. Had he really been impressed with the movie, he would have posted a positive tweet. Moreover, Balakrishna should also maintain good relations to Ntr barring any sort of egos.
