Whether the recent movie “Joy” is any good, it’s certainly different from typical Hollywad fare in one significant way. Virginia Postrel explains in a Bloomberg View column.

In the movies, an entrepreneur is more likely to be a super-villain, or at the very least a mobster, than someone who builds a significant enterprise without getting anyone killed. Even the non-murderers are miserable jerks. Take Aaron Sorkin’s angry, status-obsessed Mark Zuckerberg in “The Social Network” or his Steve Jobs in the abysmal recent movie by that name.

So it might be a surprise to discover a big-budget, award-friendly new film telling a tale of entrepreneurial ingenuity where the protagonist is heroic and the ending is happy. Except that in this case the entrepreneur is a woman. Her gender makes self-assertion, ambition, and even a touch of ruthlessness unconventional and therefore culturally acceptable.

The movie is “Joy,” starring Jennifer Lawrence as the eponymous inventor of a self-wringing “mop of the future.” Written and directed by David O. Russell (“American Hustle,” “Silver Linings Playbook”), the film declares itself: “Inspired by the true stories of daring women. One in particular.” The one is Joy Mangano, whose Miracle Mop and other household inventions made her a multimillionaire thanks to the advent of home-shopping television. …

… “Joy” is more than a wholesome paean to girl power. It’s a portrait of entrepreneurial gumption, with a protagonist whose journey is as relevant to men as to women. On her way to fame and fortune, Joy must reawaken the creative spark dampened by her dysfunctional family, solve practical business problems of financing and distribution, confront her self-doubts, find her persuasive sales voice, and subdue adversaries who take advantage of her inexperience and trust.
