Though it begins with the catfishing and hacking incident that affected thousands of Tegan and Sara fans, not to mention Tegan herself, Fanatical dips into the more general topic of fandom and explores both the good and bad of it. Tegan and Sara make for an excellent case study for two reasons. One is that they came into the social media world earlier than most pop stars, and two is that their fanbase back then was uniquely comprised of young queer people. They were vulnerable and eager to connect online, which “Fegan” or the Fake Tegan who catfished their fans, exploited to no end. The documentary does well both as an explainer of fandom and as an exploration of this unfortunate event. Where it fails is as a true crime documentary. Director Erin Lee Carr approaches some of the more unwilling interviewees with a strange sort of aggression, making the documentary feel uneven at times, if not outrightly biased.
