I still haven't seen it yet, I've been so busy lately.
But Nowhereboy I can tell you as someone who DID live in NYC during the Alig years, there was soooooo much more going on around town that had nothing to do with the club kid movement whatsoever, and the general public will not be seeing that portrayed in Party Monster (and, on artistic grounds, I can certainly understand why the producers chose to focus on one specific scene).
Those other scenes however are what I tend to remember more. Like Boy Bar, Squeezebox, Jackie 60, Save the Robots, Love Machine, and Channel 69 and Blacklips at Pyramid. And those were just the parties. The clubs themselves had so much to offer like Traxx, Mars, Club USA (briefly), the old Sound Factory, the Mike Todd Room at the Palladium, and the little tiny clubs like the old Crobar on 10th Street that had the best music .... it was completely off the hook and the beauty of it all was the sheer number of choices at your disposal. And how well everything co-existed. Back then it seemed at times that there were not ENOUGH clubs to hold all the people going out. The Alig/club kid movement was an important part of all that, but certainly not the be all and end all. Well, I'll get off the podium now.
