I saw the trailer on BLASTR, the other week. I was intrigued so I downloaded the book and read it (virtual) cover to cover. Mind you, I thought the movie "Fido" was brilliant. I am looking forward to this one as well.
Now, I think that this actually looks interesting. I will definitely watch it. It doesn't look like a Twilight ripoff at all. If anything it might be self-consciously playing with the idea, but it seems to be much more intelligent than Twilight was ever capable of being.
