The Atoning offers considerable romance and epic storytelling not seen in the audience, Reds or Doctor Jivago or Windy Past. (Yes, I deliberately give the British Patient from this list.) If we accept it, this is a very powerful sentence.
This is not just a perfect reflection of movie quality, but a description of the classical cinema style attained by Atoning. Many modern Hollywood love stories are obsolete with small and tiny stones (false identities, ridiculous lies, and other formal investigations). When cute jokes like The Heartbreak Kid go for romance, we seriously need old-fashioned events of the heart.
