I read your topic with very good interest. I am writing back to you to let you know about what I think regarding film viewing. First of all, a film ,as I always imagine, is an attempt to depict reality. As long as a language learner is interested in language learning, films could be of great help to display the culture of the target language. It present many life aspects which would make things easier for the learner. In addition, films are an audiovisual tool which enables learners to both listen and watch the language in action. However, film viewing isn't free from some dictations that make the film viewing lesson completely useful for the learners, what I meant here is that we should pepare a viewing sheet to analyse the film.
thanks for raising the point.
