Citizen Kane: The greatest?

I love film. Period. I love to watch them, take them in and think about it while enjoying them. With that said, before last week, I had never watched "the greatest film ever made" called Citizen Kane by Orson Welles. It was not the fact that I was not interested. I just never found the time to sit and watch the film. I didn't know what to expect in watching this film. It reminded me of a post-modern film like the work of Tarantino. So many jump cuts on editing were prevalent, jumping from eerie scenery and sound, to jubilant music and bright. Citizen Kane took the uncommon approach of focusing on the memories of people who were associated with a larger than life dead man. While it may appear that, as an audience, we are looking at objective point of views, human memory is flawed and for the most part, one-sided. All around this film, excluding the accounts characters from the film made, Kane was larger than life. For example, Xanadu, the gargantuan estate built by Kane is the name of a city built by the Chinese Emperor Kublai Khan as a "Summer retreat". Even by looking at Orson Welles while making this film, we can see that Citizen Kane was made to be a larger than life film, something that had never been done before until that point. The question is not why or how the focus is on a dead man, but why and how Citizen Kane is larger than life.
