What is considered the greatest movie of all time?

It's an intriguing question, indeed. When it comes to determining the greatest movie of all time, there are countless factors to consider. Is it the cinematic masterpiece that pushes the boundaries of filmmaking? Or perhaps it's the one that resonates deeply with audiences, leaving a lasting impression? Or could it be the film that has stood the test of time, remaining a classic for generations to come? As a movie enthusiast, I'm curious to know your thoughts. What criteria do you use to measure the greatness of a film? And based on those criteria, which movie would you consider to be the greatest of all time? Is it a timeless classic like Citizen Kane, a groundbreaking work of art like 2001: A Space Odyssey, or perhaps a modern masterpiece like Parasite? The answer, of course, is subjective and up for debate, but I'm eager to hear your perspective.
