Very Natural feeling and wonderfully romantic. If you wonder whether a movie can sustain interest by merely showing two people having conversation, while walking around Vienna, then Before Sunrise might be your answer. I personally found it enjoyable. It is true its main characters spout a lot of youthful pretentiousness, but that is rather the point of the movie, I believe. Whatever else, Linklater can hardly be faulted for attempting something a little off the beaten path, stylistically speaking.
