This season is absolutely amazing. It is by far my favorite. It guest star’s 3rd Rock From the Sun’s funny man John Lithgow and introduces a new character to the Miami Homicide team in Detective Joseph Quinn (Desmond Harrington).

Plot: The plot of this season is much like the plot of Season 1 where there is one serial killer for the main story. A few, small serial killers manage to make their way onto Dexter’s table but mainly, all you have to worry about is just one main killer. By this time, you know that Dexter has a son named Harrison (after his father Harry) and is living in a house in the suburbs with Rita and her two children Aster and Cody. Well now Dexter finds out about this killer named Trinity who kills in three’s. This information is of course found out by his sister Debra’s ex-lover Agent Frank Lundy. Dexter finds out that Trinity has a family just like him…a wife, son, daughter and he has been able to kill people for over 50 years without being caught. AND he’s raised a family at the same time. Dexter, instead of killing him once he’s figured out who he is, befriends him to try and find out his secrets and to find out more about him.
Family Rating: Same as Season 3 with very little nudity. (You get to see Lithgow’s rump a few times. Oh joy!) It has the same amount of language and violence.
