It's too dull to merit a real trashing but I feel the need to spend a couple of minutes giving it a slightly disinterested slating.
The artwork feels vaguely derivative of better cartoonists, at times it comes across as a bad pastiche of Robert Crumb. The stories when they aren't pointless, mundane and self-obsessive, feature characters that an imbecile would avoid creating for fear of ridicule.
The only chapters worth a glance are When Good Bombs Happen to Bad People and More Women, More Children, More Quickly. The former is interesting at first but goes on far too long after it's point is made. It consists of a lengthy chain of quotes but I'll give Sacco credit for the research involved. The latter story is by far the best thing in the book but hardly essential reading.
I've not read anything else by Sacco, perhaps his good reputation is justified by his other works. On the strength of Notes From a Defeatist, I'm not inspired to explore them.
