The story has plenty of mystery with the enemy, overarching political themes that add to the realism and depth, and lovable characters that make us want more. The OST is god-tier and it's no surprise because it's Hiroyuki Sawano and Kohta Yamamoto who did the OST for things like AoT. And the animation is absolutely stellar. The action is quite literally a combo of AoT and Code Geass where our characters pilot tank mechas that swing around like ODM-gear. Yes there is CGI, but the blending of it almost gives demon slayer a run for its money. If you're still on-edge of watching this anime, go watch the 2nd opening (minimal spoilers, 1st opening is okay) to get a feel. This show is a hidden gem right now within the community.
