Why, you may ask? The behavior of human characters in The Expanse is... terrible. They fight each other, everybody has their own agenda, they behave irrationally. Case in point: in the second book (as far as I remember) an alien ship appears in the Solar system - clearly a hostile force. Earth and Mars send soldiers on the ship and what do they do? They start fighting each other. No, I do not want to believe that humans would behave that way. If you read Clarke's books, when facing the new and possibly dangerous things humans behave logically, calmly. You do not see human vs human conflict in Rama, Childhood's End, The Fountains of Paradise, Space odyssey, Sands of Mars or almost any other of his books. It's about exploration, human unity, positivism, and there is nothing of that kind in the Expanse. I could not find a single character in the Expanse that behaves in the way Clarke's characters would. I apologize for the harsh words but I refuse to believe that Clarke would write such an abomination.
And no, it is not just the Expanse's writers, I see it everywhere nowadays, it seems that the writers nowadays need to insert human conflict so they introduce whatever irrational behavior leads to it.
