Of course not even Citizen Kane is for everyone. That's why I put not-for-everyone between quotation marks.
That begs the question. Would you write a piece on Citizen Kane and write "Citizen Kane--not for everyone"? Since when did you start caring about how popular your preferred films were?
Marina and Victor are treated with respect by the filmmakers, not like sad sacks or nerds or peripheral characters used for comic relief as the "butt of the joke".
But are they like sad sacks or nerds or peripheral characters or butts of a joke? Don't they become something else when put at the center of a film,just like the maids in the 19th-century French novels of the Goncourt brothers? Or like the Fool in Lear etc.?
