Racing Daylight

I just saw this movie last night. It was odd and strange but I kind of liked it. It's not really that hard to figure out what's going on. Sadie is either going insane and thinks she's Anna Stokes, a descendant of hers from the Civil War era or Anna's spirit is taking Sadie over and it's left up to the viewer to decide which. The only part I didn't understand was did Anna get murdered? And if so, who killed her? Was it Edmund's mother? I didn't fully understand that part. In some peoples' past reviews they have mixed things up. One person wrote that Harry got killed but he didn't...they told Anna he died in the Civil War so she married Edmund while she was carrying Harry's baby but Harry wasn't dead...he came back and he and Anna ran off together. And one person wrote that Sadie lived in Cedarsville her whole life, but she hasn't...she came back to take care of the grandmother. The cupboard where the letter from Anna was found was very mysterious so u don't know if Sadie is going insane or if Anna is a ghost possessing her. Another interesting part about the movie is that at first it seems like Henry thinks that Sadie is a weirdo but then you see things from his perspective and realize he's just as strange as her.
