Sonu Ke Titu Ki Sweety has big shoes to fill. The film, that releases today, is being marketed as almost a successor to Pyar Ka Punchnama, 2011’s cult hit. The director is the same, Luv Ranjan. Kartik Aaryan and Nushrat Bharucha also return to collaborate with Ranjan. Even the underlying theme is similar to Pyar Ka Punchnama. There are the same feminine tricks in play, and men are the victims.Sonu Ke Titu Ki Sweety is expected to have a strong box office opening of around Rs 5 crore. If the content is as good and the film is able to click with the audiences, the film could even go on to earn a sum of Rs 18 crore by the end of the weekend.
