Well, the archive footage was great and especially great to see Nancy Richey (then and now). Loved her honesty in the little interview from the early 70s when she answered she didn't know how long her tennis career or her marriage would last. I thought Margaret Court took it on the chin about her match with Bobby Riggs.
Also interesting BJK stated she and Ilana Kloss have been together 34 years.
Some thoughts on superficialities:
* Bobby Riggs circa 1973 gives new meaning to "unkempt"
* Chris Evert's close-ups weren't kind to her this time
* BJK's ensemble at her "coming out" press conference is just classic. OTOH, Mrs Moffitt's face during that presser is heartbreaking.
* BJK's enunciation has really improved over the years. She still struggles a little with "Margaret", but I think that word will always stick in her throat
Overall, for a doco, it's a nice piece of fluff, but not much more.
