Hmm. They missed a real opportunity here. Unlike the first part, which catered for some interesting character introductions to Batman and Superman, this one basically glosses over the remaining characters. They were simply called on. For an episode arc entitled "Origins" we get little here of any origin, other than a few throwaway one-offs. Pity, that.
That's not to say there's *no* development. J'onn gets a nice flashback, although it has more to do with the enemy than his own civilisation. And we do learn quite a bit about each personality within the not-yet-to-be-formed league: Flash is the cocky one, Lantern is the sergeant type, Batman being the old-school know-it-all, J'onn the outsider, Wonder Woman the rookie, and Hawkgirl the abrasive soldier. Superman, as I'm sure everyone knows, though most dislike it, is the unofficial ring-leader.
The action is amplified from the first episode and it's actually pretty neat - who says neat anymore? - to watch seven superheroes battle against the big bads. Little things like Flash trying to show off only for Lantern to chastise him, or Batman being genuinely impressed by Wonder Woman's skills make the fight scenes even more enjoyable to watch.
The ending was much more satisfactory than the first part. Not only are Superman and Hawkgirl trapped, but Batman is announced to be deceased. That's a fairly edge-of-your-seat cliff-hanger, if ever there was one. And once again, the acting is superb. Bravo.
