Critic Consensus: The inherent comedy of Miami's favorite psychopath contending with domestic bliss and the unspeakable horror of John Lithgow's Trinity killer coalesce into one of Dexter's most sensational seasons.

Critic Reviews for Dexter: Season 4

There's a rote quality to his kills at this point, as if we're just marking time until his path crosses with Trinity's.

The clever creative team at Showtime keeps us salivating for the next episode.

Like all good drama, it uses heightened characters to magnify struggles we all have.

Thankfully, this season Dexter continues to play with our moral bearings, which is the show's best quality.

Highly entertaining television.

Bravo to the cast and writers. Michael C. Hall always gets his deserved praise. And if John Lithgow doesn't walk away with next year's Emmy it'll be an honest to god upset.

Audience Reviews for Dexter: Season 4


After a somewhat weaker season 3 and less focused season 2, Dexter comes out with potentially the best season to date. Time and time again Michael C Hall delivers as the thoroughly engaging Dexter Morgan. The supporting cast has always been fairly strong in this series with decently well-crafted dialogue and an eye to the little details that make a show great. In season 4, John Lithgow arrives with a titanic performance to engage viewers and provide a worthy foe. The trinity killer is the show's best villain and there a number of truly standout episodes this season. Any prolonged interactions between Lithgow and Hall are simply brilliant. The show continues a fairly frantic pace of twists and that might have started to grow old if it was not for Lithgow's amazing performance and dynamic with Hall. This central showdown thoroughly dominates this season and this is perfectly fine. There are still a number of interesting side story lines but the focus is on this new dynamic as Dexter tries to explore a man who could possibly teach him to raise a family despite his mental condition. This season defies expectations on such an odd premise and delivers another fine season. The one low point for me continues to be Dexter's dynamic with Rita and his new family. It is not because the characters themselves are poor, maybe it is a chemistry or believability problem but these sequences feel forced and awkward. The narrative purpose of this side normal life is compelling but not the execution. Dexter also continues to build on his interesting dynamic with Deborah.
