"When Harry Met Sally" has had a lasting impact on popular culture. The film's exploration of friendship, love, and relationships has influenced many other movies and TV shows. The movie's witty dialogue, relatable characters, and nuanced portrayal of relationships have made it a beloved classic.

His character arc is subtle but profound. Harry begins the film believing that love only exists in movies. He ends the film realizing that love is the "person you want to talk to at the end of the day." It is this grounding in emotional realism that makes Harry’s final monologue—"When you realize you want to spend the rest of your life with somebody, you want the rest of your life to start as soon as possible"—one of the most romantic speeches in cinema history.
