By "we" I assume you're talking about Americans rather than the rest of the world (in which case, "we" doesn't include me). Isn't it more about what a particular audience will pay money to see? The word is that Iranian culture, at this time, is richly supportive of socio-political artworks. There is an eager audience willing and able to consume eclectic cinema. By contrast, the Iranian commercial cinema is very small. I don't think it's a question of "talent" so much as a phenomenon particular to a certain space and time.
