Irish, the film seen today may seem less of an impact, but it was different for it's time, with it's final scene, ending the way it did, which was a complete U-turn from cliche at the time. Not to mention the memorable lines and acting. Definitely one of the greatest romances of all time, though not better then The Godfather to me.

Citizen Kane is hard for me to say whether it was better or worse then GF though, due to it's complete change of cinema, decades ahead of it's time, and special effects brilliance (explain with Ebert's commentary).
