Humanity, having faced extinction at the end of the 20th century, would not have entered the new millennium if it weren't for them. In 1969, during their youth, they created a symbol.

One of the best out there

It's been a long time, but I suddenly felt like writing a review for this one, so bear with me a bit.

I tend to be extremely harsh in my critiques, from a generalized standpoint at least. The first thing I see in any work are its flaws. I'm not going to lie, here. We're dealing with a piece that has many. With such an enormous cast, character development is often sudden and relatively unprovoked. Like a bad shounen title, characters that should have died magically reappear, though admittedly to ravenous applause. The endgame has some slightly short-sighted psychological portrayals (though I'll refrain on saying much more, let's say some motivations are a little ridiculous, though thematically relevant).

And yet. And yet and yet and yet. Nijuu Seiki Shounen will likely always be Urasawa's greatest work. It is to Monster what 2666 is to Bolano's The Savage Detectives, what The Brothers Karamazov is to Crime and Punishment. Nijuu Seiki Shounen is very much a work at the level of a magnum opus. It takes the insight Urasawa honed with Monster, the humor he mastered with Yawara!, and rolls it into something altogether new, strange, and wonderful. For all of its flaws, 20th Century Boys is unmistakably insightful, masterfully plotted, and utterly gripping. It is, in the end, exactly what the title implies: a work that truly deserves to be the end result of growing up in the 20th century.

I must confess this is the first manga of Urasawa naoki I have read and what a potboiler it was ! I could go on about the style and the plot and the mind boggling character development but you probably heard that in one line this one is a mystery thriller manga of the very best kind . RECOMMENDED!

another wonderful series by naoki urasawa, my favorite mangaka of all time! this is by far my favorite of his stories and one of my favorites in general. such a wonderful story line, transitioning from past to future events so effortlessly and beautifully! his portrayal of children is so very innocent and believable and their growth as characters is the thing i most prize about urasawa. you'll fall in love with many of these strong characters and they will be sure to touch your heart...i will be reading this wonderful series again and again biggrin

From Yawara! to 20th Century Boys ...

Urasawa sensei is one of the greatest mangaka I've ever know. The Plot, The Story, The Character, The Graphic is masterpiece. When I was shocked after reading one of his Masterpiece "Monster", this manga is also great too. Well, just read it and welcome to the world of Naoki Urasawa.

Turckin. I think that's what it is-- like a turkey chicken. I'm near-positive that that hasn't been said. But other than that, I'd have to pretty much regurgitate what others've been stating below me: it's ****ing brilliant. A masterpiece. Well, most of them. As far as an epic (I know, I said it) goes, especially for Urasawa, it's magnificent. Not perfect, but come on - that's gotta be painfully obvious. Who even expects something to be perfect these days, any-who? The sheer quantity of characters would make you expect that, obviously, the quality of them would in turn be downsized, but because this series is so dag-nabbed long he has enough time to flesh them out.
As the characters, to me, aside from the settings, are the most important aspect of this series, I'm not going to comment on anything else-- especially the invisible core of it all: the mystery. So, if you're ever finding yourself bored and thirsty for a good mistree, and you're reading this, then the obvious choice to make is to read this monster. Lolwhogetsit.

starts out strong, but...

This is a manga that starts out strong, with a lot of promise, but goes downhill as the story progresses. The first arc does an excellent job of developing the heroes and showing how their shared past is linked to the current world crisis. However, there's several problems that drag down this manga.

The most glaring problem is that the villains lack any appropriate motivation. There's hints that they suffered some trauma as children, but no flashback showed any trauma strong enough to cause them to destroy the world decades later. As the villains continuously execute crueler plans, it becomes impossible to ignore why these clearly rational villains would want to destroy the world.

A continuous parade of new characters, like the Italian priest, and subplots, like the Pope's sickness, are introduced to add twists to the story and then disappear completely. Scenes, like the UN introduction, are repeated numerous times to fill space. Major events that affect the world are followed by long jumps into the future with no explanation on the full consequences.

These problems aren't an issue for shorter stories, but they ruin a long series like this one. There's a clear sense that everything is happening purely to shock and entertain the reader for another chapter, with minimal effort to create a logical and coherent story.

To start with let me say that this manga has some very strong points, as well as some very weak points, therefore in my opinion it evens out.

I read the manga Monster by Urasawa, which is a masterpiece, and then found people recommending this series, 20th century boys (the series concludes in the manga 21st century boys, which basically are two volumes).

-In terms of artwork, this is a very good manga, although I prefered the art of Monster. Nevertheless the artwork outstands.
-If something else outstand more than the artwork is the storytelling: Urasawa knows how to write and keep hooked the audience, I have to recognize that.
-Character development: quite good but expected since the story takes in 20+ years.
-But, the biggest but, is the story itself: It isn't half bad and it is well convoluted (an non-linear in chronology), but it is so easy to see how Urasawa extended artificially the story by using cheap tricks: namely adding more plots after the 'final plot' and making 'new clues' of how is the supervillian. The problem is that it is so obvious, and in the way he created many loopholes he never took care of closing them (I guess he had no idea of what to do, because it cannot be blamed by length).

So overall this is an OK manga: great artwork and storytelling, fine character development, but bad story development given the how obvious it was extended and the loopholes he created.

Urasawa at his finest

For those who want to read this series, I suggest you read Monster first. I'd say that Urasawa easily topped that with 20th Century Boys. There are very similar themes in both (all-encompassing dubious organizations, enigmatic villains who are the focal points of the series and have large cults of personality around them, corrupt police, assassinations of high-profile figures, etc.) 20th Century Boys focuses on a large group of people whereas Monster was just unfolding events around Johan. However, "Friend" wasn't as disturbing of a villain as Johan, though he had his moments. The manga does well at pointing out Friend's

rather petty
motives, the actual turning point isn't mentioned until 21st Century Boys.
