He's smart, good-looking, and he's got a great sense of humor. Michael C. Hall stars as Dexter, everyone's favorite serial killer. He spends his sun-drenched days solving crimes – and moonlit nights committing them. But not to worry, our cool-blooded Dexter doesn't kill just anyone. He reserves his homicidal hobbies to talking only the lives of other killers. Some might say he's crazy, but others say he's making the world a better place.
