Pressing mute wouldn't allow me to listen to the 'real' effects now, would it? There is nothing wrong with incidental music, keep it incidental. A polar bear scratching its arse doesn't warrant a chorus of dramatic drums. This is nature and it is fascinating enough, stop trying to sell it to us as if it's a movie, Jurassic Park for example. as for the script, 'this particular beast has his mind on other things, romance is in the air and he's not afraid who knows it...' I made this bit up but hopefully you get the gist. These are animals, not humans. Johnny Morris wasn't saying what the animals really thought you know, he was making it up. Kids stuff really.
