There were so many plot conveniences, unmotivated actions, plain stupid decisions, and even a few blatantly impossible inconsistencies, and unfortunately Nikolaj Coster-Waldau's (admittedly decent) performance can't save it. I was also very disappointed in Annabelle Wallis's performance, as I really liked her in Peaky Blinders. She somehow manages to sound bored while holding a killer at gunpoint.
The film's only other saving grace is the gorgeous scenery.
