Adam Sandler plays a jeweler who is also a gambling addict in trouble with the mob, and who can't seem to stop his gambling. He is a bit of a conman because he has to be to keep at bay all the people who are after him. He is also unfaithful to his wife with a couple of affairs, so his wife is planning to divorce him.
This is actually a good performance by Adam Sandler, but my problem with the movie is that it is about unpleasant people doing bad things. In addition, the film is dropping f-bombs literally every five seconds. I didn't hate the movie from start to finish, because the ending is pretty good, but overall I found the movie to be an unpleasant experience. I feel the same way about Uncut Gems as I did about American Beauty; there is no way I want to spend two hours with such horrible people. There is an unpleasant tension as Adam Sandler's character goes from bad to worse. The Guardian said, "Uncut Gems is so stressful it should come with a panic attack warning. Adam Sandler thriller is brilliant, but watching it is a horrible experience." I feel the same way.
All the tension in the film does make it somewhat watchable. I actually considered walking out of the movie, but I wanted to see how the movie ended, so I stayed. I am glad that I saw the ending because it is the only redeeming part of the movie.
Maybe the movie serves as a cautionary tale about the dangers of addiction.
