Break Point is the kind of movie where a drunk jerk is ready to retire but instead makes one more run at glory, and we're supposed to trot along like a ball boy. It's ostensibly about tennis, while not actually getting into the rules or psychology of the game other than a good gag where a clerk (Adam DeVine) advises Jimmy to rub his balls against his actual balls to feel superior over his opponent. We know that there are serves and backhands and fault lines, but the rest is a sweaty muddle. After a match, lead Jimmy (Jeremy Sisto) is accused of throwing the game. Really? It's impossible to tell -- the moment is the filmic equivalent of a foot fault.
Gene Hong's script plays like a random automatic serving machine. Ideas bounce all over the place, only to be quickly followed by another. There's a subplot about Jimmy falling in love with a chat-room sex worker (the bubbly Jenny Wade), a larger one about Jimmy and his estranged brother Darren (David Walton, solid) reconnecting as teammates more than ten years after Jimmy dumped him for a pro. Can methodical Darren temper Jimmy's wild serve? Perhaps. Karas showcases the actors' surprisingly good tennis skills. But rather than develop these two as characters, Break Point tries to score too many points, lobbing in a rivalry between Jimmy and his ex-partner, plus Darren's crush on a veterinarian (Amy Smart) who works for their widowed dad (JK Simmons), a romance that is hard to encourage when her boyfriend Gary (Vincent Ventresca), a slick hair-dye baron, proves one of the funniest highs of the movie.
