UNCUT GEMS by Josh and Benny Safdie Adam stars Adam Sandler as Howard, a diamond dealer dangling on the edge of the abyss. His relationship with his wife (Idina Menzel) is imploding; he owes a hefty chunk of money to pissed off racketeers who would find kneecapping too gentle; and he is sinking into the quicksand of an escalating scheme to make a fortune by selling a diamond to Boston Celtics forward Kevin Garnett (playing himself and looking good). – Gregg W.
