Nostalgia never gets old. A whole lot of the movies on this list are concerned with the past. "Pulp Fiction" is obsessed with the '70s. "Forrest Gump," "The Sandlot," "Goodfellas" and "That Thing You Do" all are nothing if not wistful about the '60s. And, well, "Sleepy Hollow," "Titanic" and "Shakespeare in Love" all look back more than 100 years. Now look at us, revisiting these '90s movies and getting nostalgic about the nostalgia. The never-ending cycle continues and grows ever more incepted.
