Some of my favourite films include Martin Scorsese's The Departed (2006), Christopher Nolan's The Dark Knight (2008), and Darren Aronofsky's Black Swan (2010).

Watching the first season of Dexter made me realized the common motif of those films: There is no distinctive boundary between good and evil; a person is bound to struggle through moral dilemma and project imperfection.

Dexter Morgan's effort to be normal and abide moral principles. Harvey Dent, the white knight of Gotham who eventually becomes a two-face. Undercover identity of the good cop and the bad cop. Nina's alteration followed by the unleash of her emotional control. These characters in the movies and TV show have shown the very human nature beneath their skin and intrigued my thoughts.

In one of the episodes, Dexter says the following monologue, which I'm carefully guessing the founding idea of the show: "Everyone hides who they are at least some of the time. Sometimes you bury that part of yourself so deeply you have to be reminded it's even there at all. And Sometimes you just want to forget who you are altogether."

Dexter is unique own its way; It's funny. It's a thriller. It's dangerous.
