For me, the movies are like a machine that generates empathy. It lets you understand a little bit more about different hopes, aspirations, dreams and fears. It helps us to identify with the people who are sharing this journey with us.
Films that the late Roger Ebert
(1942-2013) considered, in a series of essays, the Greatest Movies Ever. Note that he didn't rank them, because he dismissed the idea of Great Movies ranking. For those unaware of who Roger Ebert was, he was one of the most respected film critics ever, which is the main reason this list has its own page.
He started writing the essays in the late 1990s
, partially as a way to expand the horizons of younger moviegoers who often reject older movies out of hand. No genre was off-limits (or medium, for that matter; several animated films were written up), and no movie was too well-known or unknown. While available online, many of these essays were collected and published in book form as well.
There are a large number of movies that are considered great by others that won't be on this list, especially recent films, but that doesn't mean the film isn't great, it might have just meant that he hadn't added it to the list yet(He referred to No Country for Old Men
as being a perfect movie, but it wasn't added to the list before he died), as he did wait some years after the film had been released before adding it to see it's impact.
