I first watched the film about a year ago as I like watching controversial films from the 70's/80's and had somehow managed to miss this film. The fact Al Pacino starred also made me want to watch it.
Like the previous reviewer stated it is not for homophobic people. While I am not homophobic I found some of the scenes in the background of the clubs unnecessary and maybe they didn't need to be shown.
Overall it is a very good film and worth watching.
As a note the film caused major uproar upon release mostly from the gay community as they thought it showed an untrue image of the gay scene in New York at the time.
