Pedagogic Metalanguage about Forrest Gump

My favorite English video is a clip from Forrest Gump，which uses pedagogic metalanguage.The clip told that Gump kept running without a particular reason.We can see from the clip that he had an indirect gaze with us.This interesting clip is involved with long，medium and short shots.Gump used a peaceful intonation when narrating what he has done .The color lighting is bright,which indicates Gump is positive to life.
