The filmmaker’s choices of what to include regarding socio/historical aspects of childbirth seems personal rather than scientific to me, at least as much as I could tell from the interview. I’d prefer either a pan-global look at overall differences or else a truly local comparison to cut down at least some of the variables: say, a compare-&-contrast of childbirth expectations for white married women in Boston MA in 1600, 1700, 1800, 1900, and 2000.
