Brilliant, misunderstood movie.
I've seen this 4 times - it's hilarious and brilliant. Unlike Boogie Woogie, it's not meant as a mean-spirited trashing of the art world. Instead, it invites us to choose our own threshold between art and *beep* The point it's making is that this threshold is subjective and best defined in retrospect. Critiquing art that teeters on the line between cutting-edge and *beep* through the eyes of a musician whose work does the same, is a great non-judgmental way of posing the question: what is art? The film makes no attempt to answer the question. Instead, it gives us witty vignettes of people trying to figure out the answer on their own.
This isn't fare for Cineplexes - it's an art house movie about art. I'm amazed, though, that so many of the critics trashed it. It clearly hit a nerve with some of them who teeter on the edge of *beep* themselves.
