 Passage 3:Among intellectuals, critiques of Japanese cinema grew in the 1910s and eventually developed into a movement that transformed Japanese film. Film criticism began with early film magazines such as Katsudō shashinkai (begun in 1909) and a full-length book written by Yasunosuke Gonda in 1914, but many early film critics often focused on chastising the work of studios like Nikkatsu and Tenkatsu for being too theatrical (using, for instance, elements from kabuki and shinpa such as onnagata) and for not utilizing what were considered more cinematic techniques to tell stories, instead relying on benshi. In what was later named the Pure Film Movement, writers in magazines such as Kinema Record called for a broader use of such cinematic techniques. Some of these critics, such as Norimasa Kaeriyama, went on to put their ideas into practice by directing such films as The Glow of Life (1918), which was one of the first films to use actresses (in this case, Harumi Hanayagi). There were parallel efforts elsewhere in the film industry. In his 1917 film The Captain's Daughter, Masao Inoue started using techniques new to the silent film era, such as the close-up and cut back. The Pure Film Movement was central in the development of the gendaigeki and scriptwriting.
