Lots more character tidbits and everyone gets their moments except Batman, who seems uncharacteristically silent during the Demon's chastisement. The Flash gets lots of little bits, and Wonder Woman doesn't seem the naive island girl anymore. J'onn gets the lion's share of the screen time, and actor Carl Lumbly makes the most of it. The writers also give him some more imaginative uses for his powers: the density-increase and the elongation beneath the Demon.
The guest characters are good although Morgaine doesn't get much further time or development and the Demon is much more of an anti-hero. The main problem is that the ending just kinda...well, ends. J'onn's betrayal/redemption is good but it's way too easy to destroy the Stone (and why didn't they do that earlier?) and Morgaine just kinda shrugs and leaves. A tad on the anti-climactic side. Overall, though, a strong two-parter.
