I love this show with Professor Brian Cox. He draws you in with his knowledge and enthusiasm. You are in a beautiful trance listening to his learned voice. But towards the end, all of a sudden, the spell is broken. Another voice emerges, then another, and heads appear, sometimes even saying the first part of a sentence with Brian Cox finishing it. Why are these other people needed after he has been the sole presenter for most of the show. Are they needed? The answer is a resounding No. Do they contribute anything extra to the program? Again a resounding No. Do they detract from the enjoyment of the show? A resounding Yes. Methinks, it has something to do with diversity requirements. Am I right? Brian Cox is perfectly capable of presenting the show all by himself from beginning to end. Let him do that, for pity's sake.
