People go to these movies to see monsters fighting. There’s a lot of monsters fighting in KOTM, but you can’t see it lol.
All joking aside, KOTM tried to have it’s cake and eat it too with trying to mimic the “from our perspective massive scale” angle of Godzilla ‘14 while also delivering a lot of monster action and it didn’t really work. Every fight just feels like background to whatever the humans are doing.
I also think people have a hard time taking these things seriously. KOTM takes itself way too seriously. It tries to keep the tone of the first film and a similar tone to the original ‘54 film, but when you have a ton of monsters fighting, the “awe and terrifying” aspect loses its appeal a bit. Less is more in that regard. I think it’s easier for us to imagine one giant monster arriving and attacking and still feel somewhat grounded. It’s harder for us to imagine four or five of them who literally bow to another one at the end and take it seriously. GvK is much more aware of this. I don’t think the actual jokes work at all, but even with the jokes falling flat, the tone it sets is much less serious and much more “have fun and enjoy Giant Monke and Giant Lizzzard” which is all the average person wants in something like this.
