Yelp is bracing for a fight as a forthcoming documentary accuses the online media company of being a bully. 
The film, Billion Dollar Bully, is executive produced by Michael Levine, a longtime Hollywood public-relations man who is making his first foray into filmmaking. 
Yelp, founded in 2004, allows users to post positive and negative reviews about stores, restaurants and other businesses they have used. 
The independent film from Prost Prods. is called Billion Dollar Bully and it makes the case that Yelp is something akin to the mob, allegedly demanding “protection” money, lest your business be overrun with negative comments.

A trailer posted online, and embedded below, ominously refers to Yelp’s “filtered reviews” and features legal experts and others alleging horror stories about the service.
