New York Times called it a "low-budget freak show/cult classic/cultural institution" with "catchy" songs. Geoff Andrew, of Time Out, noted that the "string of hummable songs gives it momentum, Gray's admirably straight-faced narrator holds it together, and a run on black lingerie takes care of almost everything else", rating it 4 out of 5 stars. On the other hand, Dave Kehr of the Chicago Reader considered the wit to be "too weak to sustain a film" and thought that the "songs all sound the same". In 2005, the film was selected for preservation in the United States National Film Registry by the Library of Congress as being "culturally, historically, or aesthetically significant". Cult following Origins The Rocky Horror Picture Show helped shape conditions of cult film's transition from art-house to grind-house style. The film developed a cult following in 1976 at the Waverly Theatre in New York, which developed into a standardized ritual. According to J. Hoberman, author of Midnight Movies, it was after five months into the film's midnight run when lines began to be shouted by the audience. Louis Farese Jr., a normally quiet teacher, upon seeing the character Janet place a newspaper over her head to protect herself from rain, yelled, "Buy an umbrella, you cheap bitch." Originally, Louis and other Rocky Horror pioneers, including Amy Lazarus, Theresa Krakauskas, and Bill O'Brian, did this to entertain each other, each week trying to come up with something new to make each other laugh. This quickly caught on with other theatre-goers and thus began this self-proclaimed "counter point dialogue", which became standard practice and was repeated nearly verbatim at each screening. Performance groups became a staple at Rocky Horror screenings due in part to the prominent New York City fan cast. The New York City cast was originally run by former schoolteacher and stand-up comic Sal Piro and his friend Dori Hartley, the latter of whom portrayed Dr. Frank N. Furter and was one of several performers, including Will Kohler as Brad Majors, Nora Poses as Janet, and Lilias Piro as Magenta, in a flexible rotating cast. The performances of the audience were scripted and actively discouraged improvising, being conformist in a similar way to the repressed characters. On Halloween in 1976, people attended in costume and talked back to the screen, and by mid-1978, Rocky Horror was playing in over 50 locations on Fridays and Saturdays at midnight.
