What movie should everyone see once in a lifetime?

My coworker asked me the question this morning and I couldn’t come up with an answer. If you're a movie lover, you know that some films have the power to leave a lasting impact on us. They stay with us, inspire us, and challenge us to think differently. So, what movie should everyone see once in a lifetime? It's a difficult question, but it's worth exploring. Watching a great film can broaden your horizons, expose you to new ideas, and help you see the world in a different way. Whether it's a classic or a modern masterpiece, there are certain films that everyone should experience at least once. Who knows, it may become my favorite movie too and enrich my live in a way I never thought possible.
