While I agree the focus should be on quality, Villeneuve is the epitome of style over substance. Hell, he even basically says that himself in the second paragraph:
“Frankly, I hate dialogue,” the filmmaker told the publication. “Dialogue is for theatre and television. I don’t remember movies because of a good line, I remember movies because of a strong image. I’m not interested in dialogue at all."
Also, a lot of TV has very good storytelling, something Villeneuve clearly considers a low priority. He is not the one we should listen to about what makes a good movie IMHO
