Episode 8 Nocturne
Interesting exercise in what Batman would do with a villain that was a child. Great stuff. In the end he shows her compassion instead of leaving her to die in the sunlight. Nice to see gradually we see a bit more of an empathetic Batman.
To be honest, Batman's behavior was pretty much predictable. It might have been more interesting to have made Nocturna such an energy junkie that she ended up killing some of those kids--that would have made Batman's ethical decision harder for him to make, and would have given it greater weight. In any case, I found Nocturna a rather ho-hum villainess, especially next to full-grown vamp proposed for BTAS.
I know b.t. said the first-season writers couldn't get that version of the character to work, but maybe it would have been wiser to have postponed using the character then. If the show can have full-fledged ghosts then it could have had an episode with a vampire Batman (just as the Golden Age comics featured a vampire-werewolf like the Monk). And the show could have used a really alluring but sinister femme fatale (Catwoman is great fun but not sinister). That said, Nocturna wasn't originally a vampire in the comics; that distinction belongs to Dala (also the first female villain in Batman comics), and she could easily step into the sinister vamp/femme fatale role if the show is still interested in such a character.
