The acting from Adam Sandler in particular, but all of the cast in Uncut Gems is good with the story they had to work with.

As a dark commentary on greed, this movie only has one speed... chaotic. And while I believe it is the intent to show the chaotic world of the main character, with no change in tempo and little story or character development this movie turns into a 2 hour scream fest with sprinkling of over the top gore for the material.

The concept is there, but very poor execution of script and filmmaking by the saddle brothers.
