I avoid anything with Grisham's name on the credits so I didn't see it...what was the aspect you object to? Just curious.
The bereaved widow is suing the firearm manufacturer in civil court.
An evil cabal of firearm manufacturers secretly meet and retain the services of Gene Hackman, a jury consultant who is willing to break dozens of federal laws for a price.
John Cusack plays a slacker who is secretly a brilliant jury manipulator. He dodges Hackman's vetting process, and therefore is risking his life as the two play cat and mouse.
It is revealed that he has done all this for a woman (Rachel Weisz) whose sister was killed in a school shooting years before, and his manipulation of the jury to force the firearm industry into bankruptcy is a social imperative reinforced by the passion of a man for the lady he loves.
Formulaic, treacly, two-dimensional, manipulative crap.
But it gave me some more ideas for my "inverse Grisham" screenplay.
