Dexter is a show on Showtime about Dexter Morgan, a Forensic Blood-Spatter spealist with the Miami PD. He's also has a very dark secret.. that he is a serial killer.. and he works for the police, a perfect cover!
---Without spoiling anything plot related here is a quick synopsis for anyone looking for a good reason to watch this.---
An adopted child from a young age, Dexter and his sister grew up with their loving foster father, who also happened to be an accomplished detective. His father, being a cop and all, sensed something different about Dexter, his desire to hurt things, small animals, ect, his detachment from the world, and lack of emotion toward anything. A smart detective, he recognized this for it was, that his son was heading down the road of a murderer. He does what any loving father would do of course... teach his son everything he knows, and how to get away with it. Realizing that Dexter's path would lead him only to the electric chair, he can't bear to see his son die in this way. So he give him a 'code' with which to kill by. To only go after the scum of the earth. The murderers, the rapists, the child molestors, the one's that slip through the cracks of a flawed 'justice system'. This code Dexter strives to live by, it feeds his insatiable desire to kill, and honors his father's wishes.
Dexter is a fantastic show that twists your perception of morality, and begs questions of your mind like, can you like this person? Very well written, with convincing narrative and great acting from a nobody cast that you come to know well helps its case. Be aware that this show is run on Showtime, and therefore is not bound by the heavy censoring of regular cable television. (Even though cable censors are joke nowadays) There will be no shortage of gratuitious use of blood, killing and violence. There is also a hefty bit of nudity and sexual content, with some F bombs here and there (mostly from one character). If any of these things offend you, you have been warned. Withstanding those things, nothing should deter you from seeing this entire series, as each season is very well done, and all are worth a five-star rating.
Hope this helps you if you were on the fence. :)
