I do have to give credit to Ron Howard for trying so hard to show us the power of the mind to overcome all obstacles. Howard's heart was in the right place, but unfortunately, the movie failed to demonstrate the intended message. John Nash does not overcome his obstacles completely. In fact, he is not completely able to function until he does take medication. While his struggle is appreciated, he isn't fully able to overcome his daemons, leaving this viewer feeling only despair at the end of the movie.
