Superman/Batman, Vol. 7: The Search for Kryptonite

Not a bad storyline all things considered. But its a hugh stretch from the days when Lex had to hunt the whole world to find an ounce of Green-k to almost the whole planet made of green K. Still the novelty of the two POV's makes up for the complicated plot and the individual action sequences are well executed. So go ahead and indulge if you are a fan of either of these dudes!
