I'm really enjoying Superman Unchained, even more than I expected. Issue 3 was the best issue yet.
For much so that I wrote up a piece (backofthehead.com) on the most intriguing thing to me about this Superman story Scott Snyder is telling and how much more I want to know about the Untold History of The New 52.
Definitely agree with the weak ending sentiment, but everything up to that point was total awesomeness. I was really miffed about the Juggernaut's throwaway appearance in the second issue, but he comes back with a huge vengeance in this issue.
