The first half of La Nana really views like a horror feature. At every moment, it seems that some atrocity is about to take place. Then things lighten up about half way into the film. I am not sure that it ever becomes a comedy, however. I would characterize this almost "coming of age" story as sui generis. It does not fit into any of the standard categories but conveys more of a message about how affected by other people everyone is and how everyone has the capacity to change.
