A rare miss for Johns.  This book, which started as fun one-shots with Booster coming in and out of well-known DC storylines has now entrenched itself in Infinite Crisis callback nonsense.  Having only the slightest grasp on Crisis, this particular issue is inaccessible to me.  This is a real disappointment, as the first four issues or so were on the top of my stack of reading each month.
The art, to me, was unremarkable.
