Produced and distributed by Yash Raj Films (YRF), the film has been directed by Shimit Amin and written by Jaideep Sahni of "Chak De! India" fame.
Made at a shoe-string budget of around Rs.5 crore, "Rocket Singh...", however, couldn't bring in anticipated footfalls, say experts.
"'Rocket Singh' has not at all been satisfactory and done very bad business. The occupancy has fallen to 25 percent Monday from an average of just 68 percent over the weekend, " Amit Awasthi, manager (programming and operations) of Spice Cinemas at Noida, told.
"The content is not being appreciated, as the second half is being called very slow and dull and the climax is being considered to be not at all satisfactory, " he added.
Yogesh Raizada, corporate head, Wave Cinemas echoed the same view.
"The movie lacks mass appeal - audiences could not associate with it considering its content on sales guys, etc. So, the weekend was only average but not up to expectations, " said Raizada.
"The weekend was only close to 70 percent while Monday it has fallen close to 40 percent, " he added.
The movie is the debut vehicle of Shazahn Padamsee, daughter of ad man Alyque Padamsee and singer Sharon Prabhakar. Gauhar Khan and Sharon also play pivotal roles in the movie.
"The film has been a disappointment for the industry, " said Delhi-based distributor Joginder Mahajan.
The movie also killed Ranbir's chances of a hit hattrick after delivering two back to back hits with "Wake Up Sid" and "Ajab Prem Ki Ghazab Kahani".
