Review of Smile Pretty

I recently rented this on DVD because the store labeled it as a 'hot new release.' Well, I had never heard of it but I was willing to give it a go. And it was alright and seemed believable and I was following along and wondering what was going to happen when, suddenly, it just kinda ended 'six months later.' Maybe I missed something but it just seemed to fall off a cliff there at the end. And I really didn't understand her tossing a snide remark at the investigator at the end--something about how investigators, too, were attracted to images of under-age girls. A simple 'thanks' or something like that would have been more appropriate, it seems to me.
