The film opens with what appears to be the average scenario of a young protagonist (Crowe) in a fresh situation. Yet it is the development of the plain, to tell an amazing and indeed beautiful story, that allows the audience to become involved with that which turns out to be a far less than average reality.
The film sticks well to the the story of the real John Nash, a genius whose talent is marred by mental illness, but extends this to educate its audience in the horrors of the abnormality it details. Extensive description of the condition here would potentially spoil this masterpiece for anyone who has not yet seen it, assuredly however, after watching it, no further explanation of the subject, explored through what is essentially a case study of the scientist John F Nash, seems necessary for an audience.
This film is certainly not recommendable to anyone looking for entertainment only, but for one who is prepared to be shocked, excited and taken through an emotional roller-coaster, this is a film well worth seeing.
