Rick Riordan really wasn’t a fan of how his novels were adapted for the big screen.

While answering questions from fans on Twitter, the Percy Jackson author revealed his disdain for the film adaptations of the YA books.

Riordan explained that the process of making the films was like watching “my life’s work going through a meat grinder.” He also suggested the upcoming Disney+ series based on the novels will be more true to his vision.

The author later admitted that he has actually never seen the “Percy Jackson” films after being so disappointed by the scripts. He added that he has “nothing against” the stars of the films.

The first film in the series, “Percy Jackson & the Olympians: The Lightning Thief”, was released in 2010 and starred Logan Lerman in the title role. The sequel, “Percy Jackson: Sea of Monsters” came out in 2013.
