Mike, I wish you had provided a link to the artical. I think foreign films are important because they provide a fresh perspective. I like reading foreign newspapers about our politics so I see how we look to other countries. I didn't fully understand English until I started to study Spanish.
As I understand it, foreign films had a different way of showing sexuality and violence than American films in the 50s through the 70s. Now American films are hip to showing more sexuality than the foreign films are. Some of the audience who went for that have ceased going. I like the fresh perspective foreign films provide. Sometimes they will take the time to fully tell a story without other stuff getting in the way. Frequently a foreign film will take the time to flesh out a charactor. I think this is because they don't spend so much money, time and effort on special effects.
Foreign films remember that sensuality and violence are more powerful in the mind than on the screen. I remember in Red Sorgum they talk about how they are going to flay a man alive. They never show it, but people came out of the theatre pale and told me they couldn't believe it that they flayed a man alive.
I belive that no matter how adventurous American filmakers get, a Foreign film will always have a different way of telling the story. Watch 3 Men and a Baby in French and the American remake and tell me which is better. Whatch La Femme Nakita and Point of No Return and tell me which is better. I always go for the first (Foreign) one.
People my father's generation and older use to swear that reading a novel in its origional language was much better than the translation. I'll have to take his word for it, I failed French twice and Spanish once. Thank God I can read subtitles.
