What Is Black Mirror’s “Black Museum” About?

TheBlack Mirrorepisode “Black Museum” follows Nish (Letitia Wright), who goes to the Black Museum and meets Rolo Haynes (Douglas Hodge), who owns it. He explains the story behind each exhibit. Like themost chillingBlack Mirrorepisodes, this one focuses on technology, and Rolo says that he once worked for a company that experimented on people. Like theBlack Mirrorepisode “White Christmas,““Black Museum” features a character telling a series of terrifying stories.

The story gets creepier and creepier. Rolo talks about Dr. Peter Dawson (Daniel Lapaine), who wore an implant that ended up making him feel good whenever his patients were hurting. He then hurt himself and went into a coma when he killed a man who was homeless. Rolo then explains that he wanted Carrie’s (Alexandra Roach) consciousness to be part of Jack’s (Aldis Hodge) brain. The couple wasn’t happy, Carrie was “paused,” Jack got a new girlfriend named Emily (Yasha Jackson), and that ended badly for Carrie. In a shocking moment, viewers find out that Rolo lost his job because he moved Carrie’s consciousness to a toy monkey.

Somewonder ifBlack Mirrorgot worsewhen it began streaming on Netflix, and not everyone enjoyed watching “Black Museum.” It’s one of the most intense and heartbreakingBlack Mirrorepisodes. It’s clear when Rolo is telling these stories that something is horribly wrong and that he probably isn’t being honest, and viewers sympathize with Nish from the beginning.

Penn Jillette wrote a short story called “The Pain Addict” andBlack Mirrorcreator Charlie Brooker adapted it for the first story in the episode “Black Museum.” Even though the technology described in “Black Museum” isn’t real, the episode still feels asscary and realistic as “Arkangel"because of the social issues that are hinted at here.

How Does “Black Museum” End?

TheBlack Mirrorepisode “Black Museum ends with Nish explaining that she is Clayton Leigh’s (Babs Olusanmokun) daughter. When viewers find out who Clayton is, it’s incredibly upsetting, which is of course the point.Black Mirrordoesn’t shy away from tough topics and that is true of this episode as well. Clayton has become a holograph who is in the museum. It turns out that he agreed to be part of this museum exhibit, which allows people to watch the hologram being hurt in an electric chair.

The plot twist of Nish revealing her identity is as shocking as the ending of theBlack Mirror"U.S.S. Callister” episode. This moment is proof thatBlack Mirroralways goes to unexpected places. While viewers likely had a feeling that Nish was connected to Rolo somehow, the reveal still has a big impact.

While there are alwaysgreat new sci-fi TV shows to watch, people keep returning toBlack Mirrorbecause the show asks important questions about society and how people treat each other. Of course, everyone hopes that the world will never match what is shown here as the technology onBlack Mirroris more than a little bit disturbing. Seeing what Rolo has done to Clayton and what he did in the past to people being experimented on is terrible.

As “Black Museum” speeds toward its conclusion, Nish jumps into action and becomes a kind ofhorror movie final girlwho is looking for revenge. Rolo has a hard time breathing and Nish explains that she positioned Rolo with water because Nish’s mom and Clayton’s wife Angelica (Amanda Warren) passed away because she couldn’t take seeing Clayton in an unconscious and scary form.

Nish visited the Black Museum because she wanted to hurt Rolo for everything that he has done to her family members, and she kills Rolo by moving his consciousness to the hologram of Clayton. When she activates the electric chair, everyone will remember how much pain Rolo was in. She then lights fire to the museum, which is a memorable final image. Fans would expect nothing less fromBlack Mirror.
