Superman Batman #56

Superman/Batman had been suffering and just limping along until these last two arcs.  This was the conclusion of the SuperBat arc where the powers of Superman and Batman were switched.  It was a very thoughtful and interesting take on what would happen in that situation.  The writers avoided the easy answers in favor of a more realistic approach.  I found it to be a very fun read.  You take that and throw in some Rags Morales art and you can't go wrong.
