Michael C. Hall is brilliant in Dexter, and so are Jennifer Carpenter (his sister in the TV show and wife in real life before the divorce), David Zayas and many other great actors. This show has been aired for eight seasons, starting in 2006 and it has been incredibly popular. High ratings, a lot of rumors, super intense and interesting episodes, great plot... The list goes on. Let's start with telling you what Dexter is actually all about. The main character is Dexter Morgan, and he is a blood spatter analyst for the Miami Police. That is what he does during the day and at night he kills bad people, to put it that way. In each season, he has a new villain, and that is what adds a big dose of fun to the whole show. So, Dexter is actually a serial killer and what is very fun to watch is how he manages to hide it from his sister and all the colleagues that he is working with on solving the crimes, some of which he has committed himself. In the States there has been a slogan saying that Dexter is a serial killer that we all love, and that may help you realize what he is like. He has a moral code that his dad taught him, and one of the most important principles is to kill only those who actually deserve it. One of the most memorable seasons is the one with the Ice Truck Killer, who actually wants Dexter to play his own game and that is when the whole show gets an unexpected turn and becomes even more interesting to watch.
