The thing that sticks out story-wise for me was the fact that at no time did Pacino's character seem to be simply a "bad guy" robbing the bank. Everyone from the crowd to the hostages in the bank seemed to gravitate towards him and see that he was someone they could empathize with. Another aspect of the story was the homosexuality of Pacino's character. It was at the time a very unique protrayal as most gay characters before were mostly the stereotypical overly feminine-type. Although Pacino's lover in the film comes close to that.
The sense of realism in the film was done very well. From the camera-work (lots of hand-held) to the use of location light and subtle artificial lighting, it all created a feeling that this was something that could take place in the real world. On that note, interestingly there is also a lack of a soundtrack for the majority of the film.
