It's good, but I still don't totally understand the ending (when ****2 turns out to be
?). Monster got better and better with timeskips and new characters, but 20th Century Boys got more and more confusing.
I enjoy sports manga more than most, so once upon a time I tried to track down one of Urasawa's older series: Yawara! Fashionable Judo Girl. I found the first 10-12 volumes translated, but the translation team was long since disbanded. Pretty good series, too. I was disappointed I didn't get to finish it. Maybe I should look it up again....
And I should mention: I barely ever watch anime. I've always liked cartoons and comics, but manga is faster, cheaper, easier, and (most of the time) better. The only anime I'll watch are adaptations of my absolute favorite series, or personal recommendations from friends. From my last few years of college up to the present, I read hundreds of manga chapters per year, but maybe 20-30 anime episodes per year.
