Coffe and Cigarettes generation!
I think that most people that think this is a bad movie doesn't understand what's behind every dialogue. Also, people who tried smoking or smokes and drink coffe at coffes, understands this movie more than others. Those are the ones who discuss things in real life, as the ones in the movie.
It is a cultural thing, and we who understand this movie and love it are the real "coffe and cigarette generation", irrespective of age.
