When "The Rocky Horror Picture Show" hit screens in 1975, Newsweek called it "tasteless, plotless, pointless." Do the time warp, and the Library of Congress now reveres the camp classic as "culturally significant."
"Rocky Horror" actually began as a show on the London stage in 1973, which then opened in Los Angeles in 1974 and on Broadway the next year. But it's the film that became a cult favorite. You can catch the Midnight Movie darling, which shaped the goth/glam/punk craze, on Halloween in Port Washington, Riverhead and Patchogue.
