I am half way through the episode but the one thing I noticed is the dots for eyes when the camera zooms out. It's silly looking
. I always wonder why they can't draw with a larger digital canvas and then shrink it down so those zoomed out shots wouldn't look so silly. I will edit for more comments.
Edit: I am not sure if Mamoru would survive outside of the barrier, but it seems the village wants to kill him. I feel bad for saying this but his future looks grim. Unless the group decides to go with him into the wilds. That would be pretty cool. Probably staying out of the queerat's way and kill them if they get near because I don't trust those creatures - or I am just a bad person.
