I agree, it's not very good. It's all he wants to talk about, but ironically Friedkin just doesn't seem to know much about film noir. He either repeats meaningless descriptions like "film noir literally means dark film" or broadens the genre to the point of meaninglessness. Edgar Allan Poe didn't "write" film noir, he wrote detective fiction, which is a precursor of film noir. Yes, Raymond Chandler's work is identified with film noir, but The Narrow Margin is not really similar to it. Tell us something interesting about this movie, not just vague descriptions of the genre at large. And as the other poster said, he often just gets things comically wrong. "These films [film noir] generally begin in the daylight and end in the deep dark of the soul." Except this one, I guess, which begins at night and ends in full morning daylight? I'll remember never to watch a movie with Friedkin too; he just randomly tells us things that are going to happen later in the film or even later in a scene. Why? Just wait til we see it, then talk about it.
I gave it a shot, but I turned it off after 20 minutes. Good movie, though.
Friedkin brings out the camera work quite well, and is clearly engaged by the film, but he talks about his own films too much, and he doesn't really seem to know the story for someone who watched the film a lot as he claims.
