Let's see what they got right in this travesty:

1. There was a mathematician named John Nash. 2. He did come up with something that was later called the "Nash Equilibrium". 3. He did go nuts. 4. He did (sort of) recover. 5. He did win the Nobel Prize.

Pretty much everything else they got wrong. They made his insanity much more interesting than the banality it really was. They glossed over his first child born out of wedlock who he later abandoned. They ignored the fact that his wife divorced him and never remarried him. They turned his acceptance speech into a schlocky farce.

When they say "based on a true story", shouldn't there be a significant fraction of truth present?
