For a movie called godzilla vs Kong, they really don't spend much time fighting each other. Reminds me of batman vs superman. It's never really explained why these guys have beef. It just says they "have an ancient rilvary." but that becomes irrelevant because a little mute girl says tells Kong not to hate godzilla.
There are WAY too many human characters. I really cannot distinguish between the half dozen brunette white women who are just kinda there. All the humans are just kinda there because of course they are. They are just there to repeat outloud what we just saw. For example, mechagodzilla *somehow* becomes sentient and we cut to one of the brunette white women who says "mechagodzilla isn't being controlled by us anymore". They're all just there to surmise outloud everything we just saw.
