Finally got around to starting to read my pile of 20th Century Boys and have been absolutely blown away by it. Have read 6 volumes so far and it's one of the greatest manga series I have ever read. The plot is incredibly detailed and intricate without ever being too confusing. The fact Urasawa can jump between time periods with no warning and I am still able to perfectly follow what is going on is pretty amazing. Only 1/4 of the way through but hoping it can keep up the quality for the rest of the series.
