He’s smart. He’s cute. He’s Dexter Morgan, America’s favorite serial killer, who spends his days solving crimes and his nights committing them. In season eight, Angel Batista was not always played by David Zayas. In some scenes, his son David Zayas Jr. plays the father, as the two look remarkably alike. Dexter, who is seen throughout the first season, has a large scar on his left side. Later, in season two, the scar moved to the right side, leaving the left side intact. Dexter Morgan: I’ve lived in darkness for a long time. Over the years, my eyes have adjusted until the darkness became my world and I could see. 64th Golden Globe Awards (2007). Main ThemeWritten by Rolfe KentPerformed by Rolfe Kent. Dexter is, without a doubt, one of the best shows ever made! The story follows Dexter Morgan (Michael C. Hall), the Miami Police Department’s blood spatter expert, as he solves and commits murders. He only kills bad people who have broken the law. Being a blood expert, he manages to outsmart the police at every turn. This is a thrilling and unique TV series that will keep you on the edge of your seat for the entirety of the series. Michael C. Hall is perfect for Dexter and the other supporting actors are just as great! Yes, the ending was terrible, but like Game of Thrones, Lost (or any other show with a bad ending), a few bad episodes at the end doesn’t ruin what was an overall great show and that’s… who is Dexter… GREAT show.
