There’s a strange, beautiful comfort in hitting “play” on a movie you’ve already seen a dozen times. You know exactly when the characters will laugh, cry, or deliver that line that still gives you chills — and yet, you watch it again. Maybe it’s The Office, maybe Friends, maybe Inception (if you like your comfort with a side of existential dread). Whatever your choice, you’re part of what psychologists now call “rewatch culture” — a growing phenomenon that says as much about our emotional needs as it does about our streaming habits.
