It feels so natural and intellectual. I think it best displays Nolan's personality. It feels as if it is Nolan talking at us, intelligent and to the point (unlike this post). I feel like he panders more to the audience in the dialogue of his more recent films, but with this one you really have to pay attention to catch the whole meaning of what is being said.
Well its not quotable dialogue, but I like dialogue that is loaded with information without sounding like it is. The dialogue in this is very intelligent, but also relatable, much like Nolan speaks himself.
But maybe we just like different kinds of dialogue, because I would site this and the Dark Knight as my favorite dialogue that he has written.
"Following" movie released in 1998 was one the finest movie in which Nolan has given the best of his best direction for the movie, though i didn't remember the dialogues of the movie but the thing which i like about the movie is theme, yes the theme where someone is following you, you don't even know.... what all they are noticing and many such things.... keep it up
