What Went Wrong With The Mortal Instruments? YA Box Office Movie Flop Explained

Given the popularity of Cassandra Clare’s best-selling Shadowhunters books, 2013’s The Mortal Instruments: City of Bones should have seen enough success to spawn a series, but certain missteps sealed the movie’s fate as a box office flop. The Mortal Instruments movie follows Clary Fray (Lily Collins) as she discovers she’s from a line of demon-hunting, magic-wielding beings called Shadowhunters. After Clary’s mother is kidnapped, she’s thrust into a world previously erased from her memories. She embarks on a quest to save her mom from the former Shadowhunter Valentine, falling into a local band of Shadowhunters in the process.
