I never wrote a review after I first read this one, which I think I read in conjunction with Batman: Year One and The Killing Joke. So this, too, is an origin story, probably not as good as either of these two but it does feature the great crime comics writer Ed Brubaker, who references those two important Bat-world works. And is referenced as well in Christopher Nolan's Dark Knight.
This story is about Batman's first meeting with The Joker, his great nemesis, one of the best villains in literature of all time. Good story, good dialogue, a classic.
The second story in this volume is a Green Lantern-Batman story crime detection story, which is kind of jarring in putting these two guys together, but the crime writer Brubaker showcases the Bat here as a detective, the very basis of DC, or Detective Comics, in case you forgot that. So they work on an unsolved crime together, though I am uninterested in GL here, not a great pairing. This one is just okay. I'll say 4-5 stars for the Joker story, and 2-3 stars for the GL story.
