So what's it like to watch the new concert doc 'This Is It' on opening night with arguably Michael Jackson's most rabid fans?

At a Times Square megaplex last night, hundreds of fans started lining up well before the 8 PM screening hoping to be one of the first to see the documentary detailing Jackson's planned London shows. How do I know they were rabid? Despite numerous showings on multiple screens last night, the 8 PM screening sold out as soon as tickets went on sale...nearly a month ago.
