No, I know that the Hollow Earth nonsense is nonsense. But they don't need to make up bullshit to let us know that Zilla is tough. Call him 10K tons, 20K tons, That's all probably within reason. Calling him 160K tons is freaking nonsense. He has liquid blood based on water. They even show some crap stat on how much blood he has. He simply cannot be dense enough to mass 160K tons at his size.
I can suspend my disbelief pretty far. I do, when I read fiction, when I listen to my kids, when I discuss feats of fictional characters, when I tell myself I'll only have one more glass of whisky. But trying to show me a moving, breathing animal-y thing with liquid blood then trying to show me stupid nonsense that ignores what you have shown me just t make the numbers more impressive? Yeah, nah. Just not happening. I'm not saying the movie is bad, I'm not complaining that it exists, I just don't choose to accept certain things that simply don't make sense.
For example, are you trying to say that the 150 ton number, from the 1973 thing, somehow becomes over 100 THOUSAND tons when then animal becomes 3x taller? Nope, unless you explain how he ate a crap ton of tungsten, that doesn't work. I'd accept a thousand tons readily, even 10K tons if you want to play with all kinds of stuff. Hell, he's got big shoulders, let's say 15K tons! But over 100K? Please, it's just not a thing.
