I'm ambivalent because I don't get from this documentary that the women are Devadasi per se. They are certainly sex workers, but not necessarily Yellamma temple sex workers. In parts, the documentary feels like a Lonely Planet or Global Trekker feature I watch on PBS...minus Ian Wright's wit and humor. I don't think that this documentary is accurate at all...and comes across as callous and superficial. The journalist sounds and acts as flaky as a young tourist traveling in India during a gap year, and I've seen no evidence that there was serious research done in the subject matter.
Having said that, William Dalrymple in his recent book Nine Lives, has interviewed and written about devadasi women, and their undeniable plight. Devadasi women have had a venerable history in performing a wide variety of religious functions, including sexual service...but their lives are now hard and harsh. Only marginally better than ordinary prostitutes, the devadasi system provides a way out of crippling poverty...very similar to other countries and societies.
