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.
I'm not an active follower of the Batman books, but the hype about this got me to buy #13. I liked it a lot. The build is well done. The tension starts to rise the moment the story starts.
