I do agree about the BLOODY music! The whole idea with documentaries, especially on science, is to be as objective as possible, something that is made virtually impossible by tendentious sound effects, designed to induce in viewers or listeners a particular state of mind. I've stopped listening to most BBC radio documentaries now, because they've started putting on background music almost all the time. It's really distracting on radio, when you are trying to hear somebody speaking, and I hate the way it is subliminally trying to tell you what to think, about what is being described or said.
