Will Eisner is a legend in comics and the Spirit is one of his most famous characters, but the comics in this volume fall in the first half of 1944 when Eisner had been drafted and The Spirit was being ghost-written/ghost drawn by other people. Whereas in the early volumes prior to Eisner's military service show a creator who is deft and efficient with the eight pages he was given to work with, his ghost-creators seem stymied by it. The stories often feel rushed, since they know they only have eight pages to work with and there really isn't the creativity in both style and substance we see when Eisner is at the helm.
As a historical document, we can thank the people who kept The Spirit alive while Eisner was serving, but I would be lying if I didn't say that I can't wait to get to volume 11, where I'm assuming Eisner gets back to the genius we see in the first few volumes.
