Since Joy is a David O. Russell film, the presence of a) Lawrence and b) bizarre, fizz-popping explosions of catharsis are to be expected. But the ringmaster of The Fighter, Silver Linings Playbook and American Hustle seems to have mellowed a little, which means fewer outright belly laughs, but a more layered and involving emotional landscape.

Lawrence is gritty, real and totally genuine. And, after ‘Brooklyn’ and ‘Carol’, here’s another film that passes the Bechdel Test for proper female characters with flying colours.

Playing like a slightly more reflective B-side to the director's greatest hits, his style in this film isn’t for the more cerebral audiences. But for the viewer who relates to family dysfunction, its maddening contradictions and its mercurial tenor, Joy can be painfully funny, engaging and full of relatable heartache.

That the film itself is nearly as chaotic as the clan it examines can either be regarded as an admirable artistic correlative or a crippling defect, but the splendidly dextrous cast ensures that this goofy success story, which could just easily be titled American Hustle 2, keeps firing on all cylinders in the manner of the writer-director's previous few outings.

A sunny ode to capitalism, the movie is a coy advertisement of its own. In that context, it's a whole lot better than one might expect, and loaded with talent unabashedly hawking their wares.
