When a TV show is renewed for a second series, it can be difficult to innovate and take the show in a new direction without alienating the fans of the first series. However there are times when a show takes existing plot points and character relationships from the first series and captivates the audience. This is the case with the second series of Dexter.

In the first series we established that Dexter is a serial killer who views himself as a vigilante who is ‘taking out the trash’ by eliminating the dregs of society. Dexter thinks his tracks were covered but the discovery of his previous kills on the ocean floor prompts a new investigation, this time into the ‘Bay Harbour Butcher’.

As the show progresses it becomes clearer that the culprit is part of the Miami Metro Police. James Doakes really shines here as he is the sole individual who suspects Dexter is anything more than a forensic analyst. His determination to obtain justice is a driving force for this series.

Returning characters Debra, Angel, La Guerta and Masuka all show character development in their own way. Rita’s relationship with Dexter hits a rocky patch and Dexter tries to deal with his past.

There are some fantastic new characters in series two. Frank Lundy is a special agent who was called in specifically to deal with the ‘Bay Harbour Butcher’ case. He’s a very likable detective who appears aloof but is actually a very competent and dangerous opponent. Lila is a character that Dexter meets when covering up his tracks by attending a Narcotics Anonymous meeting. Dexter’s relationship with Lila will rock the very foundations that Dexter is used to.

Overall this is a fantastic series full of twists and turns. It constantly surprises, amazes and astounds, in terms of plot and characterisation.

Dexter is a fantastic show. The cast does a fantastic job of portraying several main characters. Character development is very important and it’s definitely where the story shines through strongest.

The main character Dexter Morgan is a serial killer that targets bad criminals that have escaped justice. He also leads a double life by working as a Blood Spatter Analyst for the Miami-Metro Police Department. There are several major characters including Debra Morgan (Dexter’s sister who works for the police), James Doakes (a tough uncompromising officer who has a lot of anger within), Vince Masuka (a forensic expert), Maria LaGuerta (Dexter’s boss for most of the series) and Angel Batista (a noble officer who tries to do the right thing).

Dexter is trying to come to terms with who he is. He is an introverted individual who has a clinical view on life. He was taught by his adopted father Harry Morgan who trained him to be normal and to only take out his frustration on those who are guilty. Many of these lessons are shown in flashbacks and these are often in moments when Dexter suddenly gets a reminder of his past.

While Dexter is an anti-hero, he is an interesting individual who often goes overlooked by the general public. Each episode enhances the story and creates a believable world. The vistas of Miami are very atmospheric and definitely conjure imagery of nice sunny holidays, the complete opposite of some of the more brutal and extreme crime scenes.

The series has many twists and turns and constantly surprises the viewer. Definitely a highlight, particularly in the genre of Detective Television shows.
