In two words, really bad. The only reason I'm not rating it lower is because the few spare moments we get to see a monster are fun. Other than that the human element, as always in the US Godzilla stuff, is mind numbingly terrible.
What really kicks me in the balls is that it's not even a bad idea to have a show "explore the human element," it just has to not suck. Unfortunately, this show is miserable. Every time a character is speaking I find myself rolling my eyes. The only times I'm mostly okay with the dialogue is when we're in the past timeline. That bit is okay, but infrequent.
