A great series hampered slightly by visuals and characters who seem a little stupid (I feel they ignore some really obvious things that are really important but overall good and i can forgive them for not just doing these because some of them would ruin the story and make the Ajin basically be a joke)
Though watching the first episode I almost just dropped it due to the visuals SLOW cg characters that look somewhat out of place in the world I believe due to the realistic lighting happening.
Facial animations are AMAZING compared to normal anime, seeing a smug or just the facial expressions convey so much about how these characters are thinking.
I also love the main antagonist a breath of fresh air.
overall don't let the visuals put you off right away watch 2-3 episodes and see if you like it I know I'm excited to watched season 2
