It is not uncommon for films to include scenes that some viewers might consider unnecessary or gratuitous. These decisions are ultimately up to the filmmakers and the artistic vision they have for the film.
In the case of "The Wolf of Wall Street," the film is based on the true story of Jordan Belfort, a stockbroker who was convicted of fraud and served time in prison. The film is known for its depiction of the excess and decadence of Belfort's lifestyle, and it has been criticized by some for glamorizing illegal and unethical behavior.
One specific scene that has garnered attention is the one in which Margot Robbie's character, Naomi Lapaglia, is shown in a full b*re scene. This scene has been described as controversial and has been the subject of debate over whether it was necessary to further the story.
Some viewers and critics have argued that the scene was included solely for the purpose of titillation and did not add anything to the plot or character development. Others have suggested that the scene was intended to show the decadence and excess of Belfort's lifestyle and the objectification of women that was prevalent in that world.
Ultimately, the decision to include the full b*re scene in "The Wolf of Wall Street" was made by the filmmakers and is a matter of artistic interpretation. It is up to individual viewers to decide whether they feel the scene was necessary or served a purpose in the context of the film.
