I don't think that she was actually comparing LoS to Rape-Lay. I think that she was reminded of the box art because of the way that the scene played out in the first person perspective with Dracula's arms outstretched.
I think that because of Twilight and a lot of these "vampires" in the media nowadays people have forgotten what a real vampire is and what they really do. There is nothing good about vampires and there is nothing to love about them... I don't quite understand how they are capable of love.
