I’m going to bring up examples from a variety of mediums, so I couldn’t really fit this just under ~books or ~tv. Sorry about that.

Lately I’ve been thinking about just how much I love fiction with a good plot device, and I’ve been wondering what it is that makes these devices such great vehicles for telling an interesting story.

Death Note is the first example that comes to mind for me. The “plot device” (and I may not be using this term correctly) if the titular item, which is a notebook where, if one writes a name of a person, while imagining their face, along with a time and date, and then a set of realistic circumstances that lead to that person’s death, then it will occur as written. If nothing other than the name, time, and date are written, then the person dies of a heart attack (after 40 seconds, if I remember correctly). The main character was the right kind to have acquired the book, because it enabled the story to be told in the manner that it was. I think the author illustrated this well when, at the very end, another character, not nearly as intelligent as the previous owner of the Death Note, quickly got done away with.

Code Geass is probably one of my favorite animes of all time. It combines a lot of genres into one. The titular “geass”, however, particularly the one that the main character acquired—which allows him to give a one-time order to any person who looks in his eyes, which the person will see through no matter what—is also an excellent plot device.

*The Lake House, a 2006 fantasy romance film, staring Keanu Reeves and Sandra Bullock. It’s not a masterpiece or anything, but I can’t forget the whole plot device about the mailbox that allowed the male main character to send letters to the female main character two years into the past.

Dreamless is one of my favorite webcomics of all time. It’s crazy for me to think that this beautiful, entirely-colored webcomic was made available for free all the way back in 2009. I wish more people knew about it. The plot device, which is brilliant, revolves around a man and a woman who were born on the same day at the same time, but he in Japan, and she in the USA—a few years before the outbreak of WWII. From the very day of their birth, they were “connected”. Whenever they fall asleep, they begin to “see through eyes and hear through the ears of the other” until they wake up. If they both happen to be sleeping at the same time, than they see darkness but still hear surroundings. They became aware of this at very young age, learning each other’s languages and falling in love with each other since they were children. The time zone difference makes it relatively easy for them to observe each other’s lives as one sleeps and the other goes about his or her days. They embark on a quest to figure out how to meet each other, in the midst of a brutal war waged between their respective countries.

Severance is a show that everyone is talking about right now, so I don’t need to explain much to you, right? The plot device here is a chip that is implanted into people’s brains, and makes it so that their memories are split in two, based on location. At their work place, the character’s memories from the outside world are “shut off”, and they only remember what they experienced on the inside. I’m almost done with season two and this show is what prompted me to write this thread. I’ve been loving it.

Black Mirror is a show that I need to give a shoutout to, because many of its most famous episodes are centered around a very specific plot device. For me, the most impressive of these, was the one where they had these chips that basically recorded everything that they saw, and it was a normalized thing in society. I think that it was episode three. Episode eight was also interesting. It was about a society in which people’s social status was determined by their online social media rank.

I had an example in the back of my mind of a piece of fiction with a great plot device that I felt was not properly made use of. I’m sure that there are others like that, and it’s a bit sad when that happens, because there is a great idea right there, but it was wasted. I totally forgot about it though. Maybe you can think of some bad examples yourselves?

Edit: I remembered a different one, In Time, a 2011 movie about a society where people don’t age, but rather have their life spans written on a digital countdown clock on their arms. The way that people used their lifespans as currency that they could exchange was a neat idea. I didn’t watch the movie, but I read from other people about it, and it seemed to me like the concept wasn’t properly explored. Maybe I should give it a chance.

And maybe you can also think of some other good examples, plot devices in books, shows, movies, manga, anime that really blew you away. I’d be curious to hear about them because I’d like to look into them if it’s something that catches my interest.

As for what makes a plot device interesting for me, here are some points:

• It is a concept that is easy to grasp or an object the functions of which are easy to understand.
• It has strict limitations that the plot revolves around and the characters repeatedly run up against. These limitations are explained very early on in the story.
• The plot device and its origins gets gradually explained over the course of the piece.
• The story is largely centered around a small group of individuals.
