Missed Opportunity
Not really sure what this documentary is supposed to accomplish, or for whom. It felt like a museum tour in which people trotted out one piece of equipment after another, made cooing noises about how cool it was, and then promptly failed to demonstrate what it actually could do.
This advance offered unlimited amounts of gizmocity! And yet you don't then show me anything about what a musician would find interesting or useful about it. Look at all these wires! And yet what do the wires actually do?
