As I mentioned before, it’s all about the monsters and destruction, but with Hollow Earth firmly established in the Monsterverse, there’s an opportunity for there to be so much more.
We’ve seen humanity in danger due to the actions of these monsters several times over.
Hollow Earth is close to the Earth’s core, so surely there’s some risk in a massive beast causing too much trouble in that immediate area that would set the stage for an epic next film, right?
What if, hypothetically, there was a force that was capable of putting the planet at stake, thus giving the Titans a chance to band together in a battle for their own lives as well?
