The name of the movie refers to the interaction between Berg and Schmitz throughout the film. He reads to her often over the years (we find out why in the middle of the film although I noticed it early on). I found the film to be quite boring at times and extremely slow-moving. Director Stephen Daldry (who was at the helm for The Hours, a movie I loathe) does a decent job of recreating post WWII Germany but can't make up for the fact that the movie's two main characters are boring and lack much of a personality. Winslet is pretty solid in the lead role (not her best effort but she'll probably win Oscar for her history of excellent acting). She recently has come out and said that she doesn't want to do nudity in future roles. Not surprising since she had enough in this movie to last her entire career.
