So, we (and by we, i mean those of us following this bit of news) all knew it would be CGI, it was announced as such from day 2, maybe even day 1, but i wasn't actually there day 1. the animation to me looks pretty good, and this is the studio that made Knights of Sidonia, and Aijin, so their animation record as far as CGI goes, is definitely on track. we don't know too much more than: humans were driven from the earth by the kaiju, namely godzilla, and in this particular timeline, godzilla is far larger, and likely far stronger, than any godzilla to this date (including burning godzilla and shin godzilla). the planet that humanity fled to is simply uninhabitable for humans, and so they have launched a mission to reclaim the earth from the king of the monsters. Our MC, Haru is the unlucky bloke
with a hate-boner for godzilla the size of king kong who'll be undertaking this mission, alongside his plucky and colorful cast of comrades, all of whom (hopefully) boast the skills to make it in this new, hostile territory, and reclaim what was once their spot, at the top of the food chain.
that being said, my own opinion is that this anime will be pretty good, but criminally underrated.
all that said, this is a monster movie, i hope that the plot, and the non-monster characters are not one-sided, but that still falls on the backburner, the monsters make the movie, and i like what i've seen so far of the designs, and the world, so as long as we get at least KoS quality animation, and a respectable amount of battles and development, i'll be pretty happy.
