Master of suspense, Stephen King said Dolores Umbridge from Harry Potter is the greatest villain since Hannibal Lecter.
Stephen King is a world famous novelist probably best known for his ability to create truly frightening fiction (that typically adapts very poorly into films). Some of his better known works include The Shining, The Running Man, It, Misery, The Green Mile, and the Shawshank Redemption, and the Dark Tower series.
While he was writing as a book reviewer for Entertainment Weekly back in 2003, he noted that the success of any novel is due to a great villain, while pointing out that Umbridge was the “greatest make-believe villain to come along since Hannibal Lecter.” Dolores Umbridge is a large antagonist in Harry Potter and the Order of the Phoenix. A sizeable portion of the book is focused on her gradual, relentless takeover of Hogwarts and the struggle of the main characters to push against her.
