The Dark Defender - Reception

Reception

Eric Goldman of IGN called "The Dark Defender" "a very satisfying episode of the show" and thought that "so far doing a very good job" of replicating the tension seen in the first season. He was impressed by Dexter's discoveries about his birth mother and adoptive father, but called Debra's romance with Gabriel a "less successful" storyline. Writing for the Los Angeles Times, Tom O'Neil called the episode a "standout" because of the parts of Dexter's past that it explored. He stated that, for regular viewers, "this episode is a real knockout", but for unfamiliar viewers, "this whole Dark Defender bit might look pretty corny". TV Squad's Keith McDuffee believed the revelation of Laura's affair with Harry to be "certainly the most shocking moment of the episode", and thought that "One of the brilliant moments of the season so far was Dexter going after one of his mom's killers." Paula Paige of TV Guide called Dexter's monologue about his hollowness "very moving". She thought that his confrontation with his mother's killer "may have been one of the best shot in the whole series". Blogcritics' Ray Ellis praised the "razor-sharp sense of humor" seen in the episode and thought that "In a season of mostly dreary, bland series, Dexter remains the most daring show on television." Dexter and Jimenez's confrontation was named Hall's best scene by Variety critic Stuart Levine.

In a short recap of seasons 1 and 2 in Film Quarterly, J. M. Tyree called "The Dark Defender" season 2's "most intriguing episode", and compared Dexter to Batman:

When the identities of the Butcher's victims are revealed to be murderers, the public applauds him, elevating Dexter to the status of a folktale avenger or comic-book anti-hero. And indeed Rita excoriates him for disappearing at night "like Clark fucking Kent," but the FBI describes the Butcher as more like one's own "personal Batman." Batman is an apt comparison, although Dexter prefers to violate Batman's aversion to killing. Both live outside the law, "part human, part mutant," as Dexter puts it. Both cling to an ethos riddled with perplexities and contradictions. Visiting a comic-book shop, Dexter find himself transformed on a handmade superhero poster from Butcher into The Dark Defender, a protector of the city and the executioner of its predators. Vigilantes simultaneously share territory with cops and outlaws, they break the law in the hopes of helping society. ... Dexter describes being "half sick with the thrill, the complete wrongness," when the "dark passenger" inside him takes command.
