The document provides analysis of the trailers for two films: 1) A Nightmare on Elm Street trailer uses suspense and tension to captivate audiences and leave them wanting to know the plot. It appears to be a thriller based on camera angles and the way they are used. 2) The Grace teaser alludes to feminist concepts and women's studies. It raises questions about an accident, a woman who doesn't want another raising her grandchild, and blood on a baby's face.
