2013 was a good year to be bad. This year's best villains weren't just goons with guns -- although there were a few great examples of those. (Here's looking at you, Sean Penn.) We also hissed at slave-owners, inventors, seducers, producers, and a couple amazing women who left an impression without barely speaking a word -- plus another mom who couldn't stop talking and never said anything nice. With less than a month left in 2013, Voice film critics present these twenty memorably nasty characters who made us want to throw popcorn at the screen. --Amy Nicholson.
