I would argue that it's simply a matter of personal preference. I hated A Clockwork Orange. Normally I don't fault movie versions for detracting from the novels they came from, but Kubrick had such an attitude about how he thought his ending was better for the story than the original author's. He prettymuch changed the point of the story with how he presented it.
On the subject at hand: Citizen Kane is a good story, in my opinion. It's told from many different perspectives but it reveals so much about what made Kane eccentric. It also does this without shoving it all in your face in a series of dull monologues. It presented a lot of his issues--mostly in flashbacks--but I'd rather watch a series of well-designed flashbacks than watch some character sit in a bar and tell the bartender about how they were mistreated as a child. If nothing else, I find it to be a good example of how a biographical movie should be made.
