One of the biggest differences between the modern Monsterverse approach to Godzilla and his classic film franchise is focus. Legendary's kaiju offerings keep their narrative details straightforward, ensuring tangible connections between every notable character. Every monster is a Titan from the Hollow Earth, and their backstories tie together neatly. Toho threw everything at the wall to see what would stick. Gigan is a fascinating example, as he represents one of several alien invaders struggling to wipe out humanity.
