Dexter wrapped its original series run in 2013, with fans tuning in to see Michael C. Hall's blood-splatter analyst by day, serial killer by night for what they thought would be the final time. The series began strongly with Dexter facing off against The Ice Truck Killer, whilst aiming to avoid suspicion from law enforcement himself. Fans of the series were treated to a psychological game of cat and mouse. Many fans believe the show reached its peak in season four with John Lithgow's Trinity Killer, before meandering to its eventual conclusion.
