"After a long time we have seen a good love story. If people think that it is a light rom-com, it is not, it is an outstanding love story," Kunal, who saw the film at a special screening Thursday, said.
Directed by Shashank Khaitan and produced by Karan Johar, the film has Alia Bhatt and Varun Dhawan in the lead roles. Released Friday, it also marks TV actor Siddharth Shukla's big screen debut.
Kunal is impressed with all the performances and had a special word of praise for Ashutosh Rana.
"All the artists have done a brilliant job, not just Varun and Alia. Ashutosh Rana has come into a film after so long and (what a) fantastic performance. Everybody in the film has performed brilliantly. Claps in a trial are rare but this happened between scenes," he said.
Kunal added: "It is a very intelligently written film. It is very tough to write such a film and like I said, it is a love story after a long time and not a rom-com."
"Rom-coms run for a few days but love stories run for many weeks so this is a very big hit," he added.
