This makes me think of the Brian Cox wonder-tone. Everything he says has a tone of wonder so thick that I can't watch his documentaries. Presumably it works for another audience.

There's also something about his presentation that is like some version of the uncanny valley with intellectual ideas. TED talks have this quality sometimes.
I don't have this with Sagan or Dawkins even though they will often use poetic turns of phrase.
I tried explaining this to my cousin who is infatuated with Cox, but I came across as somebody with highly specific form of racism directed at just Brian Cox.
