Been a while since I wrote an editorial...
Last year, I wrote a post on a few original episodes of the animated series of Detective Conan, so episodes that are not based on the comic, but written especially for the anime. One episode I shortly talked about was episode 961 Glamping Kaijiken ("The Curious Glamping Incident"), which I wanted to discuss not because it was such a good mystery, but because it was absolutely insane. The story was written by Yamatoya Akatsuki, best known for his work for Gintama and this episode of Conan definitely was more focused on crazy comedy, with loads of story elements that didn't make any sense at all in the context, and just there to confuse/amuse the viewer. The animated series has been running almost non-stop since 1996, with over 1000 episodes now and while most of the episodes are in fact based on the manga, about a third of the episodes each year are anime original episodes, written by a variety of scenario writers. And these scenario writers usually have their own angles/gimmicks they like, like there was an early scenario writer who often wrote plots revolving around animals. So the anime original episodes often do feel very different from each other because of the different writers (even if they use the same basic setting/characters), so once in a while, you get an episode like episode 961 Glamping Kaijiken because they decided to go with a writer who aims to just write something completely silly.
Yesterday, on June 26th 2021, the newest episode of Detective Conan became trending on Japanese social media, because they had another of those batshit insane episodes. Episode 1010 Egao wo Keshita Idol ("The Idol Who Erased Her Smile") was written by Urasawa Yoshio, best known as chief writer for chaotic comedy series like Ranma 1/2 and Bobobo-bo Bo-bobo and renowned for his surreal, wacky stories. In fact, Urasawa was the mentor of Glamping Kaijiken's writer Yamatoya Akatsuki and the last few years, Urasawa has written a few Conan episodes and each time, they were considered "masterpieces" in the series because they were just so silly, making no sense at all and just being unlike a normal Conan episode in every way. I couldn't contain my curiosity, so I decided to watch all of the episodes of Urasawa just to see how insane they could be.In terms of hilarious surprises, they certainly didn't disappoint. By the end of episode 1010 Egao wo Keshita Idol ("The Idol Who Erased Her Smile"), you'll realize it's the most unnecessary story ever, but the way the story is brought and the countless of little jokes (the Akira bike!) sprinkled throughout the visuals just make it a weirdly captivating story, that manages to hold your attention better than an "average, nondescript Conan story" would. Explaining the story would be a fruitless action, because the story is honestly very, very forgettable and yet I kept watching the episode because I never knew what kind of silly joke it would throw at me next. The same holds for other episodes written by Urasawa. Episode 997 Smile no Sato no Inbou ("The Smile Village Conspiracy", original broadcast on February 13, 2021) has cartoon stock villains and a granny who flies away in a jetpack and a old lady with a veeeeeery creepy collection and it's just a parade of surreal gags and almost Monty Python-esque comedy. Episode 976 Tsuiseki! Tantei Taxi ("The Chase! The Detective Cab", July 18, 2020) comes closest to having an actual detective plot, but also features so many story elemenets that are never explained (like two brothers who sing all their lines for no reason at all!) and like most of Urasawa's episodes, it almost feels like they were originally written for another series, but reworked for Conan. There are more by Uraswa, but each one of them is nuts.
But that got me thinking. While these comedy episodes of Conan are very unlike the normal stories in Detective Conan, especially the ones based on the stories of the manga, they still work because the anime series has always had a variety of scenario writers who provide different kind of stories, even though they all still use the same basic characters. So while these episodes won't serve as a good introduction to Conan for newcomers, they can be quite fun for veteran viewers exactly because they are so different from the norm, providing a different angle to what's supposed to be a familiar setting and cast. So I was wondering, were there other examples I could think of with different authors working on a series/established cast created by someone else, and where these other writers managed to add something substantial not present in the work of the original writer (and of course something I liked)?
My first thought went out to the Gyakuten Saiban/Ace Attorney videogame series, which was originally created and written by Takumi Shuu, but later Yamazaki Takeshi was made director and writer of a spin-off series and eventually took over the main series (being head writer of Ace Attorney 5 and 6). Personally, I think Yamazaki and his team of writers managed to come up with much more solid mystery plots than Takumi, with plots written closer in the tradition of Queen with theories being built on the currently available evidence etc and turnabouts in theories based on new evidence introduced throughout a story. Yamazaki and his team brought the series much closer to puzzle plot mysteries of modern Japanese detective fiction, and I honestly feel they managed to bring a lot to the series that the original writer hadn't done.
I guess that the Gyakuten Saiban/Ace Attorney videogame series with varying teams working various entries, and Detective Conan as an ongoing animated series that has a history of featuring both stories based on the comic by Aoyama Goushou, and other scenario writers are a bit of an exception though. I guess when people think of "persons other than the original author tackling a mystery series" they are likely to think of either adaptations of pastiches. Which isn't exactly what I was thinking of at first, but for example, I remember I really liked how BBC's Sherlock 'translated' a lot of Sherlock Holmes staples into a modern day variant, or for example how the Ellery in the Ellery Queen television show was nothing like the Ellery from the novels but still presented an Ellery I could see working in the original novels.
Anyway, what are some of the examples you can think of where other people get to work on an existing mystery franchise/established world/cast created by someone else, and they managed to add something or tackle the series from a completely different angle in a way that worked surprisingly well? Perhaps a different writer managed to write more interesting mystery plots with a certain premise of another author, or perhaps an adaptation that seems to surpass the original work? Or perhaps like the Conan episodes mentioned above, where someone manages to pull off something you had never expected of the franchise (positive or negative)?
