Rewatching movies or TV shows can feel comforting because the brain already knows what will happen. This familiarity reduces uncertainty and stress, making the experience relaxing. Since there are no surprises, the brain can focus more on emotions, details, or favorite scenes rather than trying to predict the story.
Rewatching also strengthens emotional connections. Familiar characters and scenes can remind people of certain times in their lives or evoke feelings of nostalgia. In stressful moments, returning to a known story can provide a sense of control and safety. This explains why people often rewatch favorite shows during challenging periods. Shutdown123
