The film was only in 112 cinema halls across the country on August 14.
"Today's generation runs after masala films with item songs. Their sense of appreciating art films has not been developed and I think this is the reason why people are not coming to theatres to watch this film," Das told PTI.
"Earlier, I heard that commercial cinema has more appeal and impact on people's mind than serious films, and now I have witnessed it," he said.
Based on his real life struggle, actor-director Anant Mahadevan made the biopic.
The film stars Vinay Pathak in the title role, along with Konkona Sen Sharma, Ranvir Shorey, Tannishtha Chatterjee, and others.
Gour said he has donated most of the Rs one lakh amount that he got after signing the deal for the biopic.
Film trade analysts say although the film has earned accolades at the national and international platform, it lacked proper marketing and casting.
"Be it a film made with a budget of Rs 5 crore or Rs 200 crore, all the films screened in cinema halls and multiplexes have same ticket prices, then why wouldn't people rather watch "Bajrangi Bhaijan" with Salman and Karina in the lead roles?" Gupta asked.
