The story was lacking...Spoilers
To me it really did not say much other than a woman becoming or not becoming pregnant by a possible rape. And that just seemed to be all. Just look at the boards on this film and it really would seem as though most viewers had nothing much to say other than the rape or should I call it a possible rape.
The guy was a nut job and would have been a horrible father considering he became a killer because she rejected him. But it was shown or written to be not the main interest of the film. I found the rapist guy to be the only thing interesting about the film and wished there could have been a more concise story about him instead of the husband and wife baby story. It would have been better if they went down this road.
The murders seemed to be done rather sloppy and uninteresting {not that all murders are interesting] but they just only confirmed what we already knew.
The ending was just something trying to be cute, To add discussion to the film.
they would have been better with a clear ending because nothing else was interesting. The good is the part where she by hiding the truth she and her friends paid for her silence.
