Dexter is about a blood spatter pattern analyst working for the fictional Miami Police Department who also leads life as a serial killer. This serial killer has a definite code with which he struggles, questions and complies through out the series which occasionally interferes with his personal (he has got one that excludes everyone else in the universe), married and official life. Though the aesthetic effects you get differ with every season (which will be detailed below), it surely is one of the best TV series, I have seen.
