"These films however, have ambiguity built into them, because it's too easy in film to make a strident work of propaganda or advertising, which are really the same thing anyway, meaning the message is unmistakable"

Godfrey Reggio is recommending that movies can be utilized to create a clear message, such as propaganda or advertising. Nevertheless, he thinks that it is more efficient to develop films with uncertainty, where the message is not so clear. This allows the audience to analyze the film in their own method, and concern their own conclusions. By creating a movie with obscurity, the audience is most likely to engage with the movie and think about the message. Reggio thinks that this is more reliable than producing a strident work of propaganda or marketing, where the message is unmistakable. He is recommending that movies need to be utilized to create thought-provoking messages, instead of just delivering a clear message.
