The word massive is massively over used imho
It is a matter of perspective and experience.
If this is the first time you’ve seen a crack in the earth, I guess its massive.
If your experience is the Grand Canyon, its pretty small.
The problem is that to get anyone’s attention these writers think you need to modify the noun so it “grabs” you.
When my daughters would say something is “amazing” I would ask if people really stood around in wonderment at just stared at it. Or was it “good.”
