A carefully crafted film which is at once a celebration of English eccentricity and an understated examination of how families often do everything they can to avoid saying how they really feel. Felicity Jones and Luke Treadaway play the lead protagonists brilliantly, but the scene stealer throughout is the wonderful Ellie Kendrick as the younger sister Kitty. Her naivety often reveals so much about what everyone else is really thinking but just can't bring themselves to say. And perhaps the symbolism will be lost on some, but without giving anything away tortoises and a small boy's little bombs mark the path of this film with great effect.
