Set in Miami, the series centers on Dexter Morgan, a forensic technician specializing in bloodstain pattern analysis for the fictional Miami Metro Police Department, who leads a secret parallel life as a vigilante serial killer, hunting down murderers who have not been adequately punished by the justice system due to corruption or legal technicalities.
In the episode, Dexter tries to convince Vogel in letting him kill Saxon, while Hannah hides in Debra's house to avoid authorities.
According to Nielsen Media Research, the episode was seen by an estimated 2.34 million household viewers and gained a 1.1 ratings share among adults aged 18–49.
Vogel offers to give him the best treatment at a psychiatric institution, but Saxon refuses to go back again, also blaming her for Richard's death by ignoring him.
Due to a lack of progress in finding Hannah, Clayton (Kenny Johnson) informs Angel that he will leave and close the investigation.
Matt Fowler of IGN gave the episode a "good" 7.3 out of 10, and wrote, ""Goodbye Miami" spun its wheels a lot before finally landing on the fact that Vogel made a grave error in wanting to try and help Daniel.
Club gave the episode a "D+" grade and wrote, "Given the myriad of crucial flaws plaguing the final season of Dexter, it's been difficult to pick the superlative among them.
But “Goodbye, Miami” solved that problem, making abundantly clear why Dexter missed its opportunity to close strong by such a wide margin.
"[5] Richard Rys of Vulture gave the episode a 3 star rating out of 5 and wrote, "Now that he's sure to avenge Vogel's death, he seems poised for the realization that he can't run from who he really is.
Of course, nothing beyond Hannah's potential capture suggests that anything else about Dexter's secret life might come to light, placing remarkably low stakes on the climax to an unevenly-plotted season.
"[8] Cory Barker of TV.com wrote, "Dexter can keep telling us that people like Vogel are important, or trying to convince us that Saxon is a worthy adversary, but by now it's absolutely clear that the show is full of empty BIG moments and toothless characters.
"[11] Nick Harley of Den of Geek gave the episode a 2.5 star rating out of 5 and wrote, "Dr. Vogel's throat was slit in the eleventh hour, which isn't as surprising as it should have been.
Dexter did seem devastated at her loss, and at least he now has real motivation to make him want to stay and kill Saxon, but like I said earlier, it's just the demise of a character that we've only just met, so it really doesn't mean a whole lot.
"[12] Miranda Wicker of TV Fanatic gave the episode a 3 star rating out of 5 and wrote, "Save for a few key scenes, "Goodbye Miami" was a slow-moving, dialogue-heavy hour of television.
"[13] Alex Moaba of HuffPost wrote, "The Vogel storyline has had its faults - the cheap twist that revealed her connection to the Brain Surgeon, and putting too much of the season's end-game on the shoulders of a new character chief among them - but this scene was extremely powerful.
