I generally really enjoy this show, but I am getting a little bit fed up with it at the moment. The dude who plays the maths genius (I just thnk of him Mr Universe from Serenity) just gives too much expostion – every episode insists on explaining some esoteric maths idea: it seems like a not-very-subtle way of making maths look sexy. Maybe that’s the point, but… a bit more subtlety would be appreciated over here.
