Really good issue. I don't think I was blown away by it as much as others were but still, really enjoyable and bursting with ideas. Superdoom had a really interesting alagory for how Superman and superheroes have been treated over the years, and I like how it all ties back to new52 Superman as a social crusader, fighting corporate monsters.
I think my favourite thing about this issue was this version of Luthor though.
"I don't care what they say about me! I'm not a racist!"
I also thought the back up was fantastic, better than the main event for me infact.
