I have not seen a better movie than War Horse to introduce mature youngsters to the concept of war and its effects. In addition, the idea of WWI: the Great War, the war to end all wars is a history lesson only movies can make real. Besides, it's a rousing adventure.
Steven Spielberg has helmed another sentimental favorite about a boy and his horse, whom he finds after the horse has been drafted. If you marry The Black Stallion with All Quiet on the Western front, then you have an idea of the mix: audience pleasing characters, their horses, and war as in Saving Private Ryan sans the flying body parts. The trenches are well-known images by now, but Spielberg brings a measure of reality that needs not the blood and guts to transmit the horror.
War Horse is not Schindler's List because it plays the sentiment card a bit too boldly with music that demands specific responses the audience could achieve without the coaching. However, the visual imagery is stunning, more like the John Ford epic silhouetting than the David Lean expansiveness. Yet, both artists are there in Spielberg's art.
Those horses: Joe is the horse sought after by his nurturing young man, Albert (Jeremy Irvine), and both the Brit and German armies as a touchstone of the humanity the director so carefully husbands. The scene when a Brit and a German soldier suspend the war to help the horse is a memorable manipulation of the theme of war's insanity. It's not the first time an artist has taken the theme of a time out of war to show its absurdity in the face of enduring humanity.
Although the film is about a half hour too long and the director's themes too obvious, he has achieved a renaissance for old fashioned quality filmmaking: gorgeous shots, sympathetic characters, epic themes, and a plot easy to follow. Over it all favors the loving, childlike director, who appeals to the youth in us and the hope for mankind.
