This is an interesting although a bit ackward movie. Although the whole premise and most of the movie focuses on the fact that the ATP miscalculated rankings back in the 70s and that Vilas should have been #1 for 5 weeks or so we don't have any way to make up our minds as the maths are apparently very complex. However the original game footage with the likes of Connors, Anastasem Borg etc is very interesting. The movie does not address Vilas's alzheimer which is visible although not mentionned sepcifically. The contrast of trying to rewrite history while Vilas struggles with Alzheimer would have have added a human touch. The last 20 minutes of the movie are more emotional while the rest of the movie is more technical.
