"Dirty is extraordinary for its sensuality, created partly by the use of rephotography, which allows the filmmaker a second level of response to the two girls he is filming, partly because of the caressing style of camera movement and partly because of the gradual increase of dirt on the film itself, making the tactile connotations generated by rephotography grow. The spontaneity of Dwoskin's response to the sensual game of the girls is combined with the spontaneity of his response to the movie of his game." John Du Cane
