The first installment in the New Krypton arc was fantastic. It kicks it off really well, setting everything up nicely--Nightwing/Chris Kent, Mon-El, the Phantom Zone, Kandor, and Zod, Ursa, and Non. I didn't realize this was the first in the arc until I was already into it. A lot that I've already seen before makes a bit more sense now.
Geoff Johns and company set the tune with a darker Superman. He and Lois adopt the son of General Zod and Ursa, naming him Chris Kent. This Superman is willing to go further, not being as much of a boy scout.
