Dexter's eighth (and final) season premieres tonight. We have Dexter to thank for creating the Serial Killer Protagonist TVsubgenre. Without Dexter, we probably wouldn't have The Following, Hannibal or Bates Motel. We definitely wouldn't have the Lazy Halloween Costume of a Henley shirt and some fake blood on your face. Dexter's season seven premiere on September 30, 2012 earned a 1.3 adults 18-49 rating. The season seven finale scored a 1.4. How do you think it will fare tonight?
