Movies used to be nothing but dialogue. I adore Denis Villeneuve movies, his artistic style and direction, but he clearly grew up in the 70s and 80s and didn't watch movies from the 40s and 50s. He's only a mere decade-ish older than I am, and I'm not a successful movie producer/director like he is, but if he thinks television corrupted movies, then that feels to me like a rather myopic take. And good lord, Woody Allen made his living on nothing but dialogue in the movies he made during Villeneuve's formative years.
