Ok, so SPOILERS
Maggie comes to, and rather than using her cell phone to call 9-1-1, she attacks Emelie?
Maybe Emelie took her phone earlier (although this was not established), but then why not go to a neighbour? Instead she decides to just jump this lady without knowing if she was armed, alone, or etc.
This is now officially the dumbest, worst movie I've seen in years.
