Usagi Yojimbo: Grasscutter I and II - Stan Sakai

Picture feudal Japan, but replace the humans with animals and you have the world of Usagi Yojimbo. In these two trade paperbacks, ronin bunny Usagi stumbles upon an ancient sword that happens to be the center of a vast conspiracy to overthrow of the government. I enjoy Sakai's work and love his world and characters. I did think that Grasscutter II was significantly weaker than the first as vast conspiracies and historical folklore gave way to lots of fighting and a pat ending. I was also confused by the two introductions (by Will Eisner and Greg Rucka), as their insistence that Sakai's anthropomorphic characters and often classic stories adds to his work makes me think they are acting as apologists. Does anyone insist that all comics must be photo-realism and highbrow literature? Let those who think so leave Usagi Yojimbo for the rest of us.
