The BEST seasons of Dexter

Every season of Dexter ever, ranked from best to worst by thousands of votes from fans of the show. The best seasons of Dexter!

Dexter Morgan is a Miami-based blood spatter expert who doesn’t just solve murders; he commits them too. In fact, he’s a serial killer — but he only murders the guilty, so he feels justified with his lifestyle choices. His policewoman sister and his cop co-workers have no idea Dexter lives a double life; however, adoptive father Harry knows his secret, and does, in fact, help Dexter hone his “skills.” It’s a unique brand of justice for which charming Dexter feels a psychological hunger.
