I agree with an earlier reviewer that this film derives much of its effect from being set in 1962. The period feel is beautifully communicated and the plot needs to work itself out in a world where places like Athens, Crete and Istanbul were not just exotic but isolated, where holidaying Americans would still be surprised and interested to meet other Americans, and people on the run could hope to hide away. The chemistry between the three leads, who are all well played, does lack fizz and there is a clumsy and rather hackneyed third act. But the film is never less than engaging and all the better for not resorting to surprise twists. The music tries too hard to be exciting, almost as if the director thinks the visuals need some extraneous help to keep the audience interested. I think he is wrong - there is enough going on here, including some fine acting and cinematography, to appeal to audiences who like films with substance, a trajectory, and a sound sense of place and time.
