Ranveer Singh and Alia Bhatt-starrer Gully Boy has managed to impress the audience and just like the viewers, ace filmmaker Karan Johar is smitten by the film as well. The film that is ruling the box office has left a mark on KJo too, who shared a long note of appreciation, calling the film a masterpiece.

Sharing a poster from the film on his Instagram account, the 46-year-old director wrote, "When passion supersedes grass root realities...when dreams make you wake up to bigger dreams....when you wrap rap into a form of solid expression....when you tell a story that has all this and more....that's when you have a film that you can assuredly call a MASTERPIECE of modern times! Zoya Akhtar weaves a story of aspirations in the underbelly of Mumbai like a bonafide magician....she slowly reveals every trick in her genius bag and you walk away with a lump in your throat and a swag in your step! #apnatimeaayegabecomes your life mantra and all you want to do is dance the dance of great Cinema!"
