‘Love Means Zero’ Review: Tennis Documentary Could Use More Andre Agassi

Jason Kohn’s documentary “Love Means Zero” is a film about tennis, but at its heart it is also a kind of match in itself, in which the filmmaker serves and volleys and probes for weaknesses in the implacable foe on the other side of the net.

That foe, in a way, is also the subject of “Love Means Zero”: Nick Bollettieri, the controversial tennis instructor whose Florida academy taught such luminaries as Jim Courier, Maria Sharapova, Monica Seles, Mary Pierce and most of all Andre Agassi, whose relationship with Bollettieri began when he was barely in his teens, reached heights of glory and ended in acrimony in 1993.
