Seventh Son, based off Joseph Delaney's young adult fiction, The Spook's Apprentice, is set in a fantasy medieval time period where dragons roam the skies and witches are feared and hunted. The plot involves a powerful witch, known to many as Mother Malkin (played by Julianne Moore), and her clan of supernatural assassins who have been waiting for the day of the Blood Moon to arrive (supposedly, it comes once every 100 years). This will be the day that grants witches their ultimate power, thereby making them nearly invincible from the threats of an ancient order of knights known as The Spooks. The Spooks are tasked with the responsibility of defending humans from the supernatural, and in this story, are simply recognized as witch hunters. But is Seventh Son a film worthy of your time and money?
