In a film, the director sometimes needs to assert their authority and make decisions their way, even if others have different opinions. It is necessary for the director to have the final say to ensure the quality and coherence of the film. However, this only applies to non-critical aspects of the production and should not involve decisions that would ruin the plot or undermine characters. It is important for leaders to create an environment that encourages dialogue and diverse opinions, but there are instances where personal preferences can be prioritized.
