Link: Best Movie Villains.
Courtesy of the Miami Poetry Review.
Includes Frank Booth, Hannibal Lector, Norman Bates, Tommy DeVito, and Pazuzu, as depicted in The Exorcist: not as a demonized agricultural deity, but as a 1970s potty mouthed interloper. Though, on a slightly critical note, no list of screen villains is complete without Ralph Fiennes' terrifying depiction of Amon Goeth: absolutely merciless.
A splendid list with humorous commentary.
