I think that for some reason I'm not like most people who go wild for Urusawa's work. I feel the same way about 20CB that I did about Monster, too long, average art, average characters. So I'm not trying to offend anybody, this is just a review from a different perspective.

Story: First of all just like Monster, the story is far too long for its own good. There are 2 or 3 points where it could have been ended satisfactorily, but it lurched back to its feet and kept plodding along for many more volumes.

The contents of the story are very simple. Man is trying to destroy the world, people try to stop man from destroying the world. To be fair, the fact that I read all the way to the end tells you that Urusawa keeps you wondering what happens next, but god it's such a waste of time. You keep anticipating something mind-blowing, but the only really interesting revelation in the whole story is Friend's identity.

Basically, what we have here is and endlessly drug-out story like Bleach or Naruto without any of the flashy bits or fanservice that make them popular. The moments that make you stand up in your chair and go "hell yeah!" are few and far between. The second half in particular is very blatantly milking it for all it's worth.

Art: Urusawa's art style is unique, but it's not for everybody. Personally I find it very bland and uninteresting. He is particularly good at drawing facial expressions, and he really conveys they characters' emotions well, but as far as manga artists go, he's pretty mediocre.

Character: A symptom of the story being too long, there are too many characters. Because of Urusawa's semi-realistic art style, some of them end up looking really similar and it becomes very confusing by the end. Since there are so many, their personalities are somewhat shallow. The main cast is fairly solid and there are a few likeable characters in there, but I feel like the story would have been served better by a smaller, more interesting cast.

Enjoyment/Overall: I was disappointed, considering how highly-rated this series is. If you're looking for something to kill time, you could do much worse, but I wouldn't recommend putting this very high on your priority list.
