I really loved how they humanized Ivy by having her care for the orphaned children.
...And then DC killed all of the children, and had Ivy torture random innocent people to death for crap and giggles. Why, DC, why? She is the only real villainess in Batman's rogue gallery (Catwoman is more of a anti-heroine, and Harley was more of a sidekick and is now becoming more of a anti-villainess), how could they handle her so badly?
