A dark portrait of the escape of modern sports fandom taken to potentially frightening (and violent) extremes, Siegel’s directorial debut has much in common with his script for The Wrestler, particularly the close attention it pays to the details of its lower-class urban environments and the suffocating entrapment of its protagonist, whose refusal to get out of his literal box seems more a stubborn form of arrested development than an actual embrace of his life’s circumstances. Patton Oswalt’s brilliantly cringe-worthy performance as the titular die-hard Giants fan is a stirring mixture of the pathetic and the sublime—a loser you can’t help but root for.
