I guess I go against the grain on this. The notion of any “genre” being forever bound to a geological location, a specific race of crew or a finite time period in order to "rightfully" retain it's categorization just doesn’t sit well with me personally.
History is important, it births and shapes a film [insert any of the arts here] genre, but can’t it then become something much bigger than those origins? Something far more encompassing that reaches further and lives longer?
The idea of a film containing all of the tropes and stylings of a well known type of motion picture, but somehow not being able to brand itself as that because it utilized race and soil of differing lands seems off to me.
If Sergio was held to this sort of elitist genre code I wonder what he, or his international marketing campaigns, would have referred to his pictures as... because by the set of standards in question they definitely would not have been able to label them “Westerns”... as they so proudly did.
Aw well, I guess we’ll just keep throwing “neo-” in front of everything.
