2. Matty Newton (The Unborn, 2009)
Another easy choice from the horror genre is Atticus Shaffer's character in 2009's The Unborn. Now before you start this has nothing to do with the guy's medical condition but everything to do with his character Matty Newton being one irritating little b*****d. Even being partially possessed by "Jumby" doesn't take away from how annoying this guy is. He hasn't even been on screen 5 bloody minutes and he's smashing mirrors over peoples heads and carrying off like a right little jerk. The shouts of jubilation that echoed through this writer's home when Matty took a full impact blow to the chest half way through the film were enough to wake the dead. It's just a shame we weren't all allowed to line up and punch the little git too. I'd have paid the price of admission a hundred times over!
