Has it been renewed for a second season in 2009?
Summer Glau will be 27 in July, so the longer they have her pretending to be John Connor's high-school-aged sister, the more idiotic it's gonna look.
And Lena Headey will be 35 this October, which is about when gravity takes over, and chicks make the sudden leap from "hot" to "prunish".
If they don't film as many episodes as possible while these girls are still in their prime, then they're gonna end up with something akin to The Golden Girls on their hands.
