"All performances were very good. I never laughed so much. This film will make you go 'mad'," Kashyap added.
'Tanu Weds Manu Returns' is a sequel to Anand L. Rai's 2011 hit film 'Tanu Weds Manu'. In the film, Kangana has a double role.
National Award winner Tigmanshu Dhulia found the sequel entertaining too.
"It is very beautiful, entertaining and a notch higher than the prequel. It's very layered and sweet film. It's a winner," Dhulia said.
'English Vinglish' director Gauri Shinde was also all praise for Kangana's "rocking performance".
"Kangana rocks. She is fantastic. It is difficult to decide on one character. She rocked completely. Even if there is a triple role, she will rock," Shinde said.
Farah Khan loved the film to the core. She was so impressed with Deepak Dobriyal's performance in the film that she said: "I want to adopt him. He is so good in the film.
"The film is outstanding. I loved it. It is so funny. Kangana is awesome in the film. R. Madhavan, Deepak Dobriyal are also good. This year Kangana rocks again."
'Tanu Weds Manu Returns' also features Jimmy Shergill and Swara Bhaskar. It will hit the screens on Friday.
