OK, part two.
The whole "Hollow World" mythology makes no sense (Earth Sciences is the only thing I studied in high-school, and it is physically impossible. Let's say that we accept it as part of this reality.)
The plucky trio of a paranoid guy and two high-school students infiltrates a Area 51-level base by... going there and walking in. No armed sentries, security cameras... dunno, pressure plates or laser-activated alarms in sight
The Hollow World mission starts! However, they say to Alexandria Ocasio-Cortez (*) what will happen in this mission during the mission? No pre-mission briefing for those involved?
(*) Because, come on, she is AOC. Why they got her involved is a mystery.
Also: no one fired drones or other probes into the Hollow World to evaluate key elements like the effects of reverse gravity, composition of the atmosphere, potentially dangerous virii and bacteria... maybe a megasaurus waiting with its jaws open for the first stray stupid to come out of the opening?? The only way they have to see if they will survive the first five seconds is... going in?!
Astounding. I wrote the above after pausing the movie. I unpaused, and the very first thing that happened... I can now officially call myself an Hollywood screenwriter
Meanwhile the plucky trio - after surviving an acceleration of 0-610Mph in five seconds, arrives...
...I mean... They arrive in the middle of an Arena where dozens of scientists are looking straight down at them, an experiment starts... And no one still notices them?! OK.
The token comic-relief sidekick knows that this new monster is not "Robogodzilla" but "Mechagodzilla" - because one can totally know how an unknown monster is named by just looking at it.
King Kong entered the Hollow World under Antarctica. Godzilla fires his blast downwards from Hong Kong and created a tunnel, a few kilometers deep, that connects the two places. OK.
The plucky trio is finally captured. To unlock this achievement the had to go everywhere in another evil base with no surveillance cameras or stuff (not even in the room where they kept a neural-net PC based on a skeleton), and press/activate anything in sight. It was worth a wild shot and it worked. They just wanted to be captured and they were getting desperate.
There is now a direct opening between the Hollow World and the surface but not a single evil megacreature either flyes or climbs out.
Godzilla and Kong fight again, this time in the middle of Hong Kong (billions of victims). No matter how many skyscraper they do destroy, however, the overall number never changes. In HK, destroyed skyscrapers immediately rebuild themselves off screen.
"It seems that this round went to Kong!" - at once Godzilla KOs Kong for good.
Godzilla doesn't fire his breath against Kong face, from 5 yards away, and thus closing the battle, because... reasons.
Mechagodzilla is turned on and, in a plot twist everybody saw coming, immediately goes rogue. He kills the bad guy in a stunning display of monstrous, mechanical violence, but the plucky trio standing three yards from him is spared.
It turns out that the bad guy is the unsung hero of the movie. Godzilla and Kong were bound to bring untold destruction upon the World - but, thanks to him creating Mechagodzilla, they now have a common enemy and will be able to be friends.
The plucky trio can't divine out of thin air the password to a multibillion dollar project. They just can't have a break.
The plucky trio destroys the console instead, and Mechagodzilla short-circuits. Wait... Didn't it just go rogue? Why it is still connected to the console at all?
The end. Mechagodzilla lies in ruins, Godzilla returns to the sea against the setting sun, Kong returns to the Hollow Earth and everybody is happy.
Well, it was fun! Writing this I mean, not the movie...
"Yes darling, I served in the Navy for eight years. I was a cook..."
"Oh dad... so you were a God-damned cook?"
