I don't know about ya'll, but this sideline alternate Earth with Superman going nuts and taking the Yellow Ring is pretty damn awesome. :) 
 My respect for Constantine through all these DC comics only grows and grows, and this is where he really shines: Magic. The one other thing that Superman is weak to. And the build-up to this showdown is freaking cool. My bet is on Constantine even if Superman is Superman and he's even wearing the Yellow Ring and standing by Sinestro's side. This is epic as hell. 
 Oh, and there's Batman, too, but I think he's just there as a look-scary bodyguard while John does all the heavy lifting. :) Batman's also a talker. Can you believe he tried to reason with the Spectre? Silly bat.
