TV - Nina Myers, 24. Evil, evil cow. Most ongoing villains like her have a reason, or redeem themselves in the end. But not her. She was a crafty piece of work.
Film - Hannibal Lecter. Clearly. There is something stupidly scary about an incredibly smart villain.
I think Bush is the best TV or Film Villain, If I am not wrong
TV - Ben Linus, Neil Godwin
Film - Joker (predictable) or Vader
