Silver Linings Playbook

Adding two cups rehabilitation, a healthy dose of formal sanitization (some forms of behaviour are denominated sane, others are not, the film does a great job of levelling the forms by showing how their contents are socially inextricable), a dash of crisis, familial spices, and communal interstices, David O. Russell's Silver Linings Playbook cooks up a hearty robust sociopsychological feast, complete with ample servings of dancing, and football.

Could have used the Broncos instead of the Eagles and set the film in Denver but that's off topic.

Silver Linings Playbook is a believable, down to earth, well-scripted multilateral examination of mental illness, romantically busting through many of its stigmas (blame attached regardless of circumstances, . . . ) through the convivial art of cacophonic curtsies. 

Honesty is the key.

Pat (Bradley Cooper) and Tiffany (Jennifer Lawrence) proceed honestly yet lack the clean record that often rationalizes honest offbeat conversations. 

Thus, even though their dialogues make sense, it's the self-critical sense making, the acknowledgement of crucial beneficial curative aids, offensively and defensively extracted from their various social interactions, within which interconnected dialogues similarly affect their friends and family, thereby emphasizing without sentimentalizing intergenerational teamwork, that leads to a more gregarious playing field.     

In regards to where honesty becomes destructively inappropriate, the film cleverly draws several lines.

Good companion film for Jeff, Who Lives at Home.
