"There's B&W in the movie, and slo-mo, and a name that's bleeped entirely for effect, and even an extended sequence in anime. The animated sequence, which gets us to Tokyo and supplies the backstory of O-Ren, is sneaky in the way it allows Tarantino to deal with material that might, in live action, seem too real for his stylized universe. It deals with a Mafia kingpin's pedophilia. The scene works in animated long shot; in live action closeup, it would get the movie an NC-17."
