...Hill House? Please help!? I need a few key differences and similarities between the two novels, I Am Legend by Richard Matheson and The Haunting Of Hill House by Shirley Jackson. Aside from the theme of alienation in the two main characters and the fact that the danger in Jackson's novel is psychological while it is more of a physical danger in Matheson's story, I am having a difficult time with thinking of other comparisons and contrasts. Thanks so much in advance!
