Correction Needed for 'AD' Publicity Caption?

Power Star Pawan Kalyan's 'Atharintiki Daredi' is going to be the new industry hit of tollywood soon breaking all the records of previous industry hit 'Magadheera'. Meanwhile, the makers have released the 5th week and 30 days wall posters which have the striking caption 'BIGGEST HIT OF 100 YEARS OF INDIAN CINEMA'. 

Those who have gone through the caption felt that the correction is needed in the caption. As per them 'Biggest' is the superlative degree and hence, it senses 'AD' is the biggest grosser among all the Indian movies in the history of 100 years. If the word 'SOUTH' had added before the word 'INDIAN', it would have been the apt caption for the movie's status. So, the caption should be changed as 'BIGGEST HIT OF 100 YEARS OF SOUTH INDIAN CINEMA'. Let's hope, the makers will correct it next time.
