That confused me a little, since I assume he'll still have been Superboy with the Legion, what with Johns steering the reboot. Maybe he was just a really, really weak Superboy, I guess.
Anyway, I dug the issue. Superman's not as much of a dick as he appears at first. You can clearly tell he's still figuring things out for himself. I'm looking forward to his growing up a bit more, to the extent that he at least won't be taunting cops left and right, but he's kind of fun this way as a young guy still learning about the complexities of the world.
Speaking of complexity, my one disappointment in the issue was the cartoonish simplicity of the villains' eeeeevilness. I don't care that the place was scheduled for demolition or how morally bankrupt Sam Lane might be; no military commander is going to open fire in a crowded urban area of one of the USA's major cities. Beyond just being wrong and the equivalent of taking a gun to a fly, it's political suicide. Lane would lose his job for sure and probably be brought up on charges. At least the bullet train gambit at the end of the issue was subtle and couldn't necessarily be traced back to Luthor and Lane. But earlier, Lane literally just has US tanks shelling the s*** out of US civilians in crowded apartment buildings. It was ridiculous and took me right out of the issue, which I was enjoying up to that point. Morrison salvages it in the end with the clever aforementioned bullet train thing, but for those few pages where US troops are unloading on US civilians and their homes, I was just shaking my head the whole time.
Oh, and Rags' art is awesome, but that's to be expected.
