Some people will find the movie slow going. I preferred to think of it as deliberate. It is effective, I think, to develop a plot like this at a deliberate pace, instead of rushing headlong through it.

Tense war drama.

An appropriately low-key film that works as a thriller and functions even better as a tragic love story.

It is a swift, streamlined piece of entertainment, an expert thriller that serves to remind us how rare the simple competence and craft it has to offer have lately become.
