Okay, I'll put it straight to you. If Twilight was just about a teenage romance (if you can call it that), then there is no point to adding vampires into the mix. Adding vampires and saying that it is a teenage romance novel is just plain stupid.
The only reason Twilight is so popular is because it lures teenagers (mostly girls I think) with young "hot" actors. Total commercial movie, no real substance.
I can't even begin to understand what this means.
