In the final episode, the vampires and Guillermo find that the documentary crew has finished their job at the house.
Guillermo (Harvey Guillén) and Nandor (Kayvan Novak) have decided to join forces to fight crime in New York, but debate how to put their plan into action.
As Cravensworth's Monster begins to exhibit sexual emotions, Laszlo (Matt Berry) and Colin Robinson (Mark Proksch) decide to create a bride for him.
That documentary was never released because that crew felt the material was not good enough because the group's dynamics and habits never changed.
Fed up with her housemates' suggestions, Nadja breaks the fourth wall and hypnotizes the viewer into accepting whatever "perfect ending" they have in mind.
[a] Shortly afterward, Guillermo delivers a speech about everything he learned during the 16 years he lived with the vampires, but he is overshadowed by the Monster having sex with a taxidermied bear.
As the TV crew starts disassembling their equipment, Guillermo returns and awakens Nandor, explaining that he is not really moving out, and he only said he was so that the documentary could have a good ending.
[2] When asked over the ending, Kayvan Novak said, "I was aware that the writers left it quite late to decide what they were going to do with the last episode, and, understandably, they needed that time to make good decisions.
"[10] Alan Sepinwall of Rolling Stone wrote, "Somehow, some way, this unapologetically silly show about how immortality is wasted on anyone selfish enough to get it, managed to end on a beat that was as warm as it was ridiculous.
Regardless of what kind of anonymous comments Colin Robinson intends to make about the finale on Deadline, TV Guide, and Den of Geek, this great, explosively funny show in no way whatsoever biffed the landing.
"[11] Katie Rife of Vulture gave the episode a perfect 5 star rating out of 5 and wrote, "What We Do in the Shadows has kept the gothy sweethearts of the world well fed for the past six years and has earned a nice, long period of super-slumber in its coffin down in the sub-sub-basement.
At its best — which includes this series finale — it represented the pinnacle of sitcom writing and performance, not to mention some killer costuming and sets.
"[12] Ben Travers of IndieWire wrote, "amid all the delightful teasing toward emotional adieus, “The Finale” actually finds a fitting end — a real one — with just enough heft and just enough silliness to make everyone happy.
"[13] William Earl of Variety wrote, "In a television landscape saturated with complex storylines, life-changing character development and serialized moments, What We Do in the Shadows both existed and ended as a proudly silly and irreverent hang-out comedy.
"[14] Cheryl Eddy of Gizmodo wrote, "As much as we wish it would live forever, What We Do in the Shadows is indeed over, going out on an episode succinctly titled “The Finale” that wrapped up one major storyline and left others open-ended — but mostly just let us know that when it comes to vampires, nothing really ever changes.
Either way, the writers and cast have fun with the sudden stop, beginning the episode with two Shadows-ready story ideas before immediately abandoning them both.
