Tracking Edith

I would've rated this higher if more compelling information about why Edith mattered as a spy was included. The documentary makers say she changed history, but the case isn't made that well. She seems to have been a big factor in the effectiveness of the Cambridge 5, but it doesn't seem like Edith was central to that whole story. I like the inclusion of many of her photos, and I think the documentary might be more meaningful to people interested in photography rather than espionage. Interviews with her 100+ year old brother are the highlight. Some of the details about her personality and general life are interesting, but the last half hour seems a bit stilted, giving me a "Who Cares?" mindset about the whole thing.
