The National Award-winning actress expressed her views on the prevalent trend at the launch of Anupama Chopra's book "The Front Row: Conversations On Cinema" here on Tuesday.
"I feel they (paid media stories) are very harmful for the business aspect of our craft. You spend so much to buy these media net stories or full page ads to build perception... you can rather save this money and put it in the making or marketing of the film," Kangana said.
The `Queen` fame actress also added that a film's success depends on quality content.
"No one knows how much it is benefiting. If you see, a film like 'Queen' did well on word of mouth and because of its strong content. The content has to be good," she said.
The actress, who is prepping up for `Tanu Weds Manu Returns`, also highlighted the adverse effect of the trend on small budget films.
"It is true that some people are interested in the buying part of things...They want to buy everything from the movie reviews to the media net to the opinions and so on.
"It's hard for small filmmakers to survive in such situations," she added.
