The very idea behind Dexter is as original as it can get. A serial killer hunting serial killers? I immediately started binge watching it when I read the synopsis. The characters are spectacularly written especially Debra Morgan and Dexter, of course. To say that Dexter is gripping, is an understatement.
But I must agree with the people who say that Dexter falls a bit short after Season 5. Well, the writers made uninteresting choices just to somehow keep the show going.
Even with that, no man can call himself a TV-Show Freak if he hasn't watched Dexter.
