Fortitude is Britain’s biggest original TV drama commission in recent memory, with filmic visual ambition and a production budget to match. And, judging by the feature-length first episode, Fortitude is worth every penny. (…) Gråbøl takes the strength of The Killing‘s Sarah Lund and the power of Borgen‘s Birgitte Nyborg, and combines them into a performance that is resolute, forceful and just a little bit scary – yet just below the surface, there’s a feminine vulnerability that will surely clash with Odegard’s ambitions as the series progresses. – Neil Midgley, Forbes.
