good back-story, and good acting

It's the kind of movie you'll want to see a second time with someone who hasn't seen it yet, to remember what it was like to watch it for the first time.

Just intense enough to provide a much-needed diversion, just lightweight enough to make you forget about it soon after it’s over. It’s not exactly “good,” per se, but it does what it sets out to do in terms of putting us on edge, which makes it … successful?

One of the best movies of the year! Incredible from the beginning to the end.

Revelation, great movie, good actors, based on real story of real men fighting for their country and England and never giving up. Very moving, very well done, certainly can recommend to everyone!
