"Only occasionally does one of the interviewees break through all the gossipy dross with some semblance of unguarded humanity. It's difficult, for example, not to be moved by the raw confessional of video game developer Brianna Wu, whose tweets about sexism in the gaming industry unleashed a hellfire of rape and death threats, and forced both her and her husband to leave their home. At one point we see a video sent to Wu by some anonymous bully who was apparently driving to her house to kill her, but had an accident along the way. His unintelligible offscreen tirade is horrifying, and Wu's remembrance of it so deeply affecting, that it makes you wish it was contained in a much more sober and probing series."
