Zion definitely has a good story and some interestingly ambiguous characters. I'm constantly re-deciding who the good guys and the bad guys are.
In my
review of Volume 1 I expressed a few disappointments that still carry over. The speech bubbles are often ambiguous and difficult to follow. We do find out why several of the characters look alike, but it's still confusing - they could have been given more unique clothing or something to distinguish them.
