I haven't watched in a couple weeks as I teeter on the decision of whether or not to bail, but I did read something interesting today:
There are reports that they are going to re-cast Poison Ivy again at some point in the near(ish) future, swapping out Maggie Geha for Peyton List (The Flash, Smallville, Frequency, The Tomorrow People).
Not sure what the deal is, but changing the actor again seems like an odd choice, especially after they've already kind of pushed the creeper button but making the usually highly sexualized Ivy basically follow the plot of the old Tom Hanks movie Big and have her basically be a kid in a grown-up's body.
