Perception.
The last few Godzilla movies have followed the normal routine. Similar plot, characters, etc. One disadvantage when it comes to watching a movie is the viewer has no control. They're seeing someone else's vision. Yet when it comes to toys, novels, etc...they have the chance to either create their own scenario or imagine it in greater detail than any movie ever could. It's all in the imagination of one's perception.
That's my two cents.
