A film in which the speech and sound effects are perfectly synchronized and coincide with their visual image on the screen is absolutely contrary to the aims of cinema. It is a degenerate and misguided attempt to destroy the real use of the film and cannot be accepted as coming within the true boundaries of the cinema.
