This documentary analyzes Morgan Spurlock's experiment of eating only McDonald's food for 30 days. It uses a mixed documentary style as Morgan acknowledges the camera. The themes include dieting, health, fast food, and personal health impacts. The documentary has a linear, chronological narrative structure but leaves some aspects like McDonald's response and Morgan's long-term health open-ended. It employs various camera techniques like zooms and pans to document the food and locations. The main setting is within McDonald's restaurants. Both diegetic and non-diegetic sounds are used along with editing cuts and graphics to convey information and persuade viewers.
