This movie just got to me.  Amazing...for older people viewing the film it was enthralling to envision your life turning clockwise..  If only we could regress after acquiring all the knowledge of a lifetime.   The movie shows a huge clock running counter clockwise in hope of returning the soldiers who had gone to fight in the Great War.  The actual aging process of the characters is fantastic.  I believe mature viewers will appreciate this film.  It was a process just to keep track of his age as the events unfurled.  Go see it.  Great.
