Others have said that this film is an incest drama. No, it really isn't. There aren't any family sex scenes. There is one comment in the dialogue about someone suspecting they are sexual, but this is neither confirmed nor denied. Although it isn't an "incest drama," the film is focused on the unique relationship the brother and sister have. It's an interesting film and worth the watch, but note it is more of a slow burner. If you are looking for something action packed then this isn't the film for you.
