Profound and respectful portrayal of a person's fall into obsession and dysfunction after completing the pinnacle achievement of her life's pursuit only to lose purpose and meaning in everything else. Illustration of the psychological struggles and self destructive depths other historical champions might have endured such as George Eastman and Meriwether Lewis, not in the movie. Ms Portman's swagger, cougar gait and neurotic episodes were performed perfectly. I couldn't think of anything else while watching, which is the kind of movie experience I'm looking for.
