I'm re-reading Annihilation and Conquest right now, and Ronan has much more depth to his character than what is portrayed in Guardians of the Galaxy and Captain Marvel. The movies just has him as a edgy complete monster villain, destroying Xandar for the sake of evil, when really in the 616 universe, he's a far more complex character. He is like Judge Dredd or Inquisitor Eisenhorn, he has a grey and compelling morality, and though he may be a ruthless dude, it's not as simple as what is portrayed in the film. He cares about the survival of his people and the individual acts of justice, not the context. And his relationship with Crystal of the inhumans was cute. It's a shame we'll probably never get anything like Annihilation on the big screen.
