RRKPK is enjoyable throughout its run time. Ranveer Singh is stellar as the typical West Delhi Boy. Alia Bhatt looks gorgeous. The trailer had most of the funny scenes. I would recommend you to watch the movie without seeing the trailer first. The songs were not at par with KJO movies but they weren't bad either. The Old School Bollywood Movie Songs used were a saving grace. Dharam Jee & Shabana Azmi were adorable. Jaya Bachchan's character left asking for more.
Delhi locations were extensively used. The Leela Palace, Chanakyapuri doubled up as the mansion for Rocky Randhawa. There was also a scene between Alia & Jaya Bachchan which was shot at Nathu Sweets located in Bengali Market.
Overall, it's a wonderful family movie.
