Nan Goldin's film "Sisters, Saints, Sibyls" is being presented at a former Welsh chapel in London as part of Gagosian Open. The film is reported to be a provocative and gut-wrenching work that addresses themes of suicide and addiction, and is dedicated to the artist's late sister. The presentation has been reviewed by several outlets, with some noting a strong reaction from viewers, although the specifics of these reactions are not entirely clear.
