There are two formulas when it comes to rock and roll documentaries. The first is the sweeping exposé of a world-famous band or musician—you can expect some unreleased concert footage, some exclusive interviews, some new, shocking insight. The second template is the heartwarming and/or heart-wrenching story of an underdog who just won’t quit—despite ghastly drug addictions, tragic deaths, or lack of chart-topping hits—where said subject presses on, never turning their back on their passion and livelihood.
You’d best believe a documentary about Jon Mikl Thor—the Canadian body builder turned heavy-metal frontman—will fall squarely into the latter formula.
