Before the documentary, I knew very little about Dr. Ann Burgess, and as I watched it, I realized it’s not because her contributions to history were so little (just the opposite, they’re incredibly important and far-reaching) but because Burgess doesn’t like to promote herself all that much. “There are too many things to do to be bothered by all that,” she says with impressive urgency at 87. Thankfully, Mastermind director Abigail Fuller distills Burgess’ storied career into three deeply engaging episodes for all to witness and enjoy. Here, you see Burgess standardize criminal profiling and help agents capture serial killers like the notorious Ski-Mask Rapist. You also see other sides to Burgess—the nurse, mother, mentor, professor, and advocate—and you start to feel frustrated on her behalf, because she should get way more credit than what she’s been given thus far.
