I loved Action 10: while it's not my favorite nu52 series (still Demon Knights), Action might be the best series they're doing right now. I like that we still seem to be about four years or so in the past, maybe? Clark's not quite at the Planet yet. The scene with the Justice League looked pretty "early" too (and was more efficient story-telling than the first six issues of the League's own title). We seem to be developing three different sides to Superman's personality: nebbish Clark, international Kal-el, and scary-ass local Superman.
