10 Most Unexpected Horror TV Show Deaths

Taking on the often overlooked perspective of a serial killer and making it a guiding focus, Dexter's unique take on a popular sub-genre of horror made it very engaging to audiences. With its high view count and a strong performance from Michael C. Hall, it became the most successful series on the Showtime channel.

By day, the titular protagonist is a bloodstain analyst for the Miami police and at night he hunts down and brutalises those who slip through the cracks of the justice system. As he evades the authorities and struggles against his violent urges, Dexter finds himself faced with many adversaries.

Many times, this puts those close to Dexter at risk. His secret can't stay hidden forever and over nine seasons, the tension continues to rise. Rita Bennet, played by Julie Benz, marries Dexter and maintains an emotional bond throughout the first four outings.

When the sadistic Mitchell learns of Dexter's true identity, Rita is sent away for her own safety. While our anti-hero is successful in killing his nemesis, the villain ends up having the last laugh. Dexter finds Rita dead in a bathtub as the fourth season ends. It's a massive shock that weighs heavily on the protagonist for the rest of the series.
