That’s so meta…
In the midst of a career, there will be certain periods of time when you focus exclusively on your work, and your experience of the culture at large is essentially nil. Later, when the slope of your career trajectory drops off a bit (and it will), you may notice these gaps and may even want to fill them in. I’ve heard it said by many pundits that the 1970s were the peak of modern cinema, but I don’t believe it for a minute. I’m finding good stuff from every decade.
