I love this book so much. And it is almost entirely due to how Jeff Lemire writes my favorite heroes. Specifically, how he can portray them as being competent in a fight but still let the humor of their personalities conflicting with one another come through in a believable fashion. This is most apparent in the snarking between Green Arrow and Animal Man, but it also comes through in Stargirl's first encounter with Supergirl. And there is one glorious but amusing sequence where Martian Manhunter gets a laugh-inspiring moment as he deals with a group of Rannians who have threatened to imprison him indefinitely.
Unfortunately, I don't think the artwork is quite up to par with Lemire's story. Mike McKone's artwork isn't bad but - as in the first issue - he is not above recycling panels. A larger problem with this issue is the inking, which was overseen by three different inkers including McKone. As a result, there are noticeable and distracting differences in the individual pages, with some seeming to have barely gotten any inking besides a black outline around individual characters!
