Silver Linings Playbook” is a very funny, family film — about families and marriages, not for family viewing. Screenwriter and director David O. Russell wows us again with his realistic, detailed relationships, rapid dialogue and delicious situations that never totally sell out to pure quirk. There’s a lot of theology of the body in it, spoken and unspoken (and a little anti-theology of the body, too). Set in Philadelphia, Pat (Bradley Cooper) is a young married man with mental issues that caused a lengthy stay in a psych ward, and basically the end of his marriage. But Pat, newly released from the hospital into his parents’ care (his underdog, OCD, sports-obsessed father is played by Robert DeNiro with much vulnerability; and his loving, worried Mom is played by Jackie Weaver) and is determined to win his wife back. How do family and friends react to the “new” Pat? In all different ways, but Pat is blessed with some truly great support. Enter Tiffany (a “look out world, I’m only going to get better at this” Jennifer Lawrence) for one of the plainest “meetcutes” ever — but it’s perfect because these two have no use for niceties and conventions. They don’t even know how to do them. Tiffany is an unstable young widow who is as unfiltered as Pat (according to Tiffany it’s “telling the truth”). But Pat only has eyes for his wife and enlists Tiffany in his plan to win her back. Since Pat now owes Tiffany, he must join her as her partner in a dance competition, which Tiffany thinks is also a better plan to get Pat’s wife back. But then things get complicated with Dad’s plans, and all plans converge around an Eagles’ game and the dance competition. The betting that goes on around these two contests carries with it an incredibly long, convoluted and boring exposition, but no matter, the film had us at “excelsior,” “no negativity,” and “look for the silver lining.” Will a love relationship develop between these two well-matched misfits? All I can tell you is that, if it does, it will be in great part because Pat totally respects Tiffany even when she doesn’t respect herself. Burns is a Daughter of St. Paul ministering in Chicago.
