Doomsday/Fridge

I was thinking about how downright pathetic and unable to stand up for herself Cally was in Doomsday, which was weird given the writer/director's love for the Action Girl trope. It eventually hit me after reading about the main character's background - Cally was supposed to be the contrast to Eden Sinclair. Eden grew up on the streets and learned to be tough and hold her own, so now she's a super tough Action Girl. Cally would have grown up with her abusive and psychotic father and brother without a chance of holding her own, so she learned to be afraid of them and stay away from violence. -Whatever
