Jennifer Lawrence of Hunger Games fame plays an inventor housewife.
However for you patent practitioners out there, plot holes abound.
Jennifer (whose character's name is Joy by the way) tries to sell her self-squeezing mop on QVC.
But on her Dad's advice (Robert DeNiro) she doesn't use a patent attorney.
She gets herself a "textile" lawyer.
Many of the business men she runs into cheat her.
(This movie isn't just about inventors. It's about feminism.)
The spirit of her dead grandma keeps her going in the face of all naysayers and financial obstacles.
(You go girl! You don't need men telling you a woman can't do this.)
In the end, she cuts her hair (liberation).
Puts on a pair of dark sunglasses.
And has a Texas style face off with her biggest man cheater.
Don't spit in the wind. Don't pull the mask off the Lone Ranger.
And don't mess with Jennifer, middle name law and danger
