The Maysles' films are considered examples of the style known as direct cinema. The brothers would let the story unfold as the camera rolled, rather than planning what exactly they wanted to shoot, in keeping with Albert Maysles' stated approach, "Remember, as a documentarian you are an observer, an author but not a Director, a discoverer, not a controller." However, the brothers also received criticism from those who thought that they had actually planned or otherwise influenced scenes. Most notably, Pauline Kael's negative review of the film Gimme Shelter in The New Yorker included a harsh accusation that much of Gimme Shelter and Salesman had been staged and that the main subject of Salesman, Paul Brennan, was not a Bible salesman as the film portrayed, but was actually a roofing-and-siding salesman recruited as a professional actor. The Maysles brothers threatened legal action against The New Yorker after this accusation. They also sent an open letter to The New Yorker refuting Kael's claims; however, because the magazine at the time did not publish letters, the letter did not appear in print until 1996. In the case of Grey Gardens, the brothers were also accused of unfairly exploiting their subjects.
