My take on this..... well i don't find Sudeep guilty for shouting at Priya. He must have shouted as a result of reflex action. I mean that dupatta left scratches on his face..... so it must be having heavy mirror work; what if it would have hit him in the eye or something?? But i don't find Priya guilty as well..... it was not her fault that she could not dance with the heavy dupatta on...... what was she supposed to do; concentrate on her dance moves or be careful about her dupatta not hitting anybody??
Fault is of makers......who were responsible of the dance move or their clothes...... they could have easily changed that particular move to something simpler or they could have changed her dupatta with a simple and lighter one.....I mean what is more important..... designer outfit or the safety of actors ❓
