These days, film makers are pretty well educated about the giants whose shoulders they stand on, so it's sometimes fun to spot the references in their films to scenes and tropes in "classic" films. I don't believe those film makers think those classic films they reference are cliched at all, if anything they have great respect for the genius of the people who invented the visual language they use in their films. See for example Marty Scorsese's clear influence by Max Ophuls in Age of Innocence, and then the people who reference 1970s Scorsese. Modern film makers, the good ones, will watch these classic films over and over, like listening to great classical music. Certainly the average punter going to a Star Wars film doesn't care about that stuff, but surely a collector spending serious $$$ should have some of the same appreciation for that heritage as the professionals. I guess if the point is that the classic stuff seems cliched to relatively young collectors, one would hope that that attitude would change as they became more serious. Or maybe I'm just showing my age.
As an aside re Citizen Kane, I'd say Ford's Stagecoach is at least as influential; Welles watched it as he made Citizen Kane, adopting elements of Ford's visual language. The best steal constantly.
