It's an overused phrase for sure (and, ultimately, meaningless - sort of like "Rosebud"!), but calling something "the CITIZEN KANE of..." is simply a way to convey that the thing stands head-and-shoulders above the competition in terms of ambition and execution. I see it as a compliment to Welles' achievement; however, I don't see much point in applying it to anything other than filmmaking. Citing RAGING BULL as "the CITIZEN KANE of boxing movies" seems appropriate since the character arc and biographical aspects between the two films are similar and both films broke new ground from a cinematic standpoint. But is THE GODFATHER "the CITIZEN KANE of gangster films" or is THE GODFATHER the cultural touchstone itself (THE SOPRANOS is "THE GODFATHER of HBO drama series", etc.)?
I don't think I've ever used the phrase seriously myself and the more ridiculous the comparison, the funnier it seems ("the CITIZEN KANE of girls-fighting-in-their-underpants commercials" made me laugh out loud). Which film did Roger Ebert refer to as "the CITIZEN KANE of silents..."? That seems like the most absurd take on the phrase. Surely, CITIZEN KANE would be the sound era's version of the silent film he references, not the other way around.
Oh well, I love the link found at the bottom of the "magnetcat.com" site that touts a new IMAX 3-D version of KANE coming soon; the mock-up 3-D stills actually work (in a tacky Photoshop kind of way) when you pop on the old red/blue glasses!
