What I mostly see in this article is somebody putting forward some somewhat salient points to bolster their own opinion. That's to say, his is a defensible position to take, but it doesn't stand up to the very real fact that there are so many different opinions within the Godzilla fandom, and what different people prefer in a Godzilla movie, that to try to make a broad generalization like this is in itself folly.
To illustrate this, though he believes audiences are fundamentally disinterested in any human character centric plotline, the single most frequent complaint I have heard from people both inside and outside of the fandom about the 2014 film is that they were disappointed that Brian Cranston's character was killed off too early. To the same effect, I think the article understates the human element in some of the Japanese entries in the franchise.
And to insert some personal bias into this, not only am I in the camp that posits monster fights as not the most important part of a Godzilla film, but I also consider both 2014 and King of Monsters (2019) to be successful American entries into the franchise.
Like I said, so many takes inside the Godzilla fandom. Everybody has a different selection of favorites. This guy's opinion is just one of many.
