Critical response
Andrew Parker of TheGATE.ca praised the series, writing that Falardeau "masterfully paces everything and finds every possible piece necessary to form a comprehensive picture of grief, corporate malfeasance, and governmental shortcomings that protect corporations more than they do everyday citizens."
