Josh and Benny Safdie’s new verité thriller should come with a warning label that it will most assuredly produce anxiety in its audience. It is both a blessing and a curse that these sibling writer/directors fill every mise-en-scène of the paranoid action drama Uncut Gems (B) with such realistic and resounding cinematic finesse. This potboiler of a film constantly raises the stakes and develops a preternaturally tense atmosphere not to be underestimated by the faint of heart. The brothers’ mastery of charged objects nearly out-Malteses every falcon frame. Adam Sandler is incredible in the meaty antihero role at the film’s center, and the plot basically traces his diamond district hustler character through the constant ups and downs of being over leveraged. It’s not necessarily a cautionary tale since the main character was pretty corrupted from the very beginning, but it’s fascinating to see the compounding effects of his actions as he juggles bribes, bets and bids into a nearly untenable position. The central character so dominates the movie that there’s really little oxygen for others in the ensemble, so it’s difficult to want much more than a speedy resolution for all of them. It’s amazing filmmaking buoyed by a pulpy performance, but you may like it best once it’s over.
