How a critically panned horror film became a massive, record-breaking box office success
In short: The Devil Inside is widely cited as having one of the worst endings in cinema history, yet it remains a case study in commercial triumph. Despite earning an F from audiences and near-universal critical disdain, the found-footage film turned a modest $1 million budget into a $101.8 million global haul.
Released in January 2012, The Devil Inside follows a woman investigating her mother’s involvement in a series of exorcisms. The project originated in 2005 when Matthew Peterman and director William Brent Bell pivoted from a traditional script to a mockumentary style, hoping to replicate the success of the Paranormal Activity franchise. Paramount Pictures acquired the film through its low-budget branch, Insurge Pictures, and chose not to screen it for critics before its debut.
The film’s conclusion became a flashpoint for public outrage. The story ends abruptly, followed by a title card directing viewers to a website for updates on the Rossi family case. While the filmmakers argued this open-ended approach felt authentic and visceral, audiences felt cheated, with reports of theatergoers booing and demanding refunds. Bell later noted that the website link was a marketing addition by Paramount, intended to extend the narrative experience beyond the theater.
Despite a 6% approval rating on Rotten Tomatoes and a 76.2% drop in its second weekend, the film’s financial performance forced studios to rethink the release of horror movies. Previously, horror films were relegated to the dump months of January or the Halloween season, with expectations of modest returns. The Devil Inside proved that even poorly received films could generate significant revenue during off-peak periods, signaling a shift in how studios approached the genre's marketability.
Critics largely dismissed the film as a derivative entry in an exhausted subgenre, with some comparing it unfavorably to The Blair Witch Project. While a few reviewers found it suspenseful, the consensus was that it failed to deliver on its supernatural premise. Ultimately, the film stands as a strange intersection of marketing, audience frustration, and a pivotal moment in the economics of modern horror cinema.
