This is an extraordinary movie allegedly based on the Durst real estate family of New York. It's a bizarre story, and the acting of the principals, Kirsten Dunst, Ryan Gosling and Frank Langella, is terrific and, on occasion, terrifying.
I'm not going to tell you about the plot -- it is ridiculous. For me to even discuss it would take away whatever pleasures might be there. But if I were you, I would do what most audiences have done: not go.
I rarely like slow-moving films that take their time setting the scene for more adventurous or violent moments to come. But I was comfortable watching this movie, which is beautiful and well worth watching.
