The Short List put together a list of the top 25 TV villains:
When it comes to the Idiot Box, villainy rules. And who better to learn from, but the 25 greatest TV villains? Be careful, people, this way mischievous wickedness lies…Topping the list, not surprisingly, is one King Joffrey Baratheon of Houses Baratheon and Lannister, First Of His Name, King of the Andals, the Rhoynar and the First Men, Lord of the Seven Kingdoms and Protector of the Realm.
Which is a great testament to the acting skills of Jack Gleeson, who portrays Joffrey on HBO's "Game Of Thrones". He captures the malevolence, the insanity, of what some called "Aerys The Third" perfectly.
