Those wondering, according to Yamazaki, "Minus One" refers to the level of where Japan had to start when rebuilding Japan after WWII. If the atomic bombing of Japan was the countries lowest point in history ("0"), then the emergence of Godzilla puts them lower ("-1").
As many have mentioned, this movie goes back to Godzilla being the bad guy versus a hero/antihero that Hollywood has been making in the last 10+ years.
Unlike more recent Godzilla movies made in the US, the human story is very specific on how to deal and overcome Godzilla and the aftermath of WWII, which is good; not too overbearing as other Godzilla movies with the human element to it.
If you can ignore the Japanese only speaking and some bad CGI (here and there, not too bad), then this is a good movie to go see during a thin month (Dec 2023) of blockbuster movies.
My biggest criticism, wished the hospital scene was more dire or devastating (you'll know what I mean when you see the film).
And yes, there is a post-credit.
