Actually it needs a movie about its production
I'm watching it right now, and frankly, one thing is clear from minute 20 in the movie, crystal water clear, this is a movie that you can't blame the actors, nor the Village People, nor the writers, nor Nancy Walker. There are hints here and there of what the film could have been without execs and producers telling them what to do... It killed - or almost killed - many careers and it's of course a bomb and specially an insult to the gay community itself (the first "openly" gay band to suceed and they always surround the boys with girls, inducing they would be actually straight, not to scare audiences).
Can you actually believe that by the same date gay community - but the leather one - was protesting against "Cruising", which actually didn't chicken to show gay facts - even if extreme - as they really are?.
I'd love to watch John Waters, Todd Haynes, Gus van Sant, Alejandro Amenabar or Pedro Almodovar (just to mention 5 great gay filmmakers) take on how this movie was conceived and done, how Hollywood wanted to start gayxplotation, disneyfying it.
