Twilight in 3 bullet points:
1) Girl is created with pretty much no backstory, appearance, distinguishable personality traits, or anything otherwise identifiable, in such a way that most females on the planet can relate to her
2) Guy is created by author that is pretty much perfect in every way (and is described as such), and falls profoundly in love with girl
3) Since most females can relate to Ms. ??? and most of those enjoy the romantic fantasy that they can vicariously live, the series has high female approval ratings whereas most guys read it and go "dafuq?"
[x] Good appeal
[x] Good marketing
[_] Good writing
