I loved it. Wow, did I love it. Better than I hoped, I'm kind of stunned by how good it is. Grant Morrsion and Rags Morales deliver the most dynamic, exciting, action-packed Superman in years. (With no small bit of help from Spider-Man 2...)
Avengers: The Enemy within #1 Age of Ultron #8 Iron Man #10 AoU is fun imo. They changed the story around, going from the current world dominated by Ultron to the past where they go after Pym to the current world again...where things are different now.
