Pluto is a mature adaption of one of the most iconic arcs of Astro Boy. The manga, by the same name, is widely considered a masterpiece and is a deep passion project for the writer. I want to keep this mostly spoiler-free.
Every single character from the original arc in Astro Boy has been given justice in this remake. Atom (Astro Boy Himself) and Gesicht are the main leads of this show and both of them never fail to keep me engaged. The suspense is all very well done and the conclusion to it all is personally among my favorite endings in fiction.
I would highly recommend going into this blind, and if you love Seinen anime/manga, you will have an absolute blast here. Pluto comprises some of the most well-written and heartfelt characters whose story reaches a perfect end. Pluto isn't just another humans & robots centred story, it is THE humans and robots centred story.
Going into Pluto I knew we would get a brilliant adaption because the project was led by Masao Maruyama. He founded Madhouse and MAPPA, who specifically founded this new studio to adapt extremely well-deserving and overlooked mangas akin to Pluto.
Moreover, some of the other masterpieces he produced are Monster, Perfect Blue, Death Note, Hunter x Hunter (2011), Nana, Trigun, Hellsing Ultimate, Paprika, Kids on the Slope, and Tokyo Godfathers, among many others, the guy has been the driving force for masterpieces left and right. Also, the music composition is being done by Yuugo Kanno, who is well known for his extremely popular JoJo opening themes.
The Mangaka Naoki Urasawa is well known for his genius in developing murder mysteries or suspenseful tales that get increasingly interesting as you read. He has genuinely created some of the most masterful stuff in modern entertainment, and to finally see this manga by him get such a phenomenal and passionate adaption feels so good; I waited for so long to get one. I hope that Pluto is successful enough that we get an adaption of 20th Century Boys, which is another manga by Urasawa.
