@G. H. (Gman) Yeah, now that you've pointed that out it does make a lot more sense. To loosely use an old meme "Maybe it's not the movie the world deserved, but the one it needed?".
Thinking about it, this could also explain why certain parts of the movie felt like a puzzle with certain parts missing. Maybe the movie was heavily re-edited to better fit this more casual mindless fun theme instead of the more thought-out plot of the previous movies. Maybe that's even why the trailer took so long to come out? I'm going down a whole new rabbit hole of conspiracy theories, but I'll let you decide.
It also does explain a lot why I and some others didn't like this movie as many others seem to do. For me personally, I really enjoy those more brainy and meaningful elements in movies, especially with Godzilla/Kaiju movies. It's the same reason why I stopped with the Fast and Furious franchise, just stuff happens for reasons unknown, physics just doesn't matter until they do? Godzilla movies especially have always had that more meaningful perspective on it, heck without it the big G wouldn't even exist. Then again, Godzilla has always changed depending on the times, going from an effect of war to a superhero to a force of nature to the embodiment of dying soldiers. It's weirdly always been part of the character.
As you mentioned, I'm really interested to see how in 5 years or so people will look back on this movie and if it will hold up as well as it does now. If anything I hope people will at least start to notice some of the flaws the movie has on rewatch. I hope if the Monsterverse continues, they do lean back to the more plot-driven stories of the previous movies, but only time will tell I guess.
