Story: At the beginning the story starts off as a mystery/thriller with the series of robot murders and then slowly turns into more of an action/mystery. The interesting part with Pluto is that it touches a bit on the psychology of robots while having the horrors of war to begin a cycle of hatred that plays a major role throughout the story affecting the characters deeply.
Characters: For those of you who have read Astro Boy or is just familiar with the cast of characters will realize that Atom is "Astro Boy" and notice the return of Dr. Ochanomizu and Tenma Umatarou also as I mention above that detective Gesicht is very similar to the of Monster's detective Lunge with some alterations. The characters do a very good job of following the story and are very well developed.
Content: One of the things that surprised me about Pluto was the content, it has (I believe) no blood or language (being that half the characters are robots). Absolutely no nudity or anything like it. Mainly anything content wise would be all the lives lost in the war talked about and some of the crimes committed that are mentioned. Overall probably one of the cleanest mangas i have read so far.
Art: The art is (if you are familiar with any Urasawa's other works) easily recognizable. Being somewhat similar to Death Note's having a very realistic portrayal of people versus some of your mainstream art leaving out the real detail of human features allowing Urasawa to really capture the full impact of human emotions.
Conclusion: I having watched the animated version of Monster am already a fan of Urasawa and if you are likewise you will really enjoy Pluto also. Urasawa starts off by sucking you into the story right alongside the characters all the way to the end.
Should you happen to be new to any of Urasawa's works Pluto in and by itself is a very good manga and I also suggest you check out some Urasawa's other works such-as Monster anime or manga (the anime directly follows the manga), 20th Century Boys or any of his other works.
