This is a bland Moe show that is clearly using the idea of angels and demons as a thin skin.
Do you want to know the basic difference between a demon and an angel is?
The idea of good and bad is purely a human concept which we use to ground are morals (something they don’t need).
Ditching these extreme ways of being for human vessel just seem like a waste of potential jokes. I like the idea of an angel being corrupted by a computer game, too bad there is no straight man for her to stand out as an anomaly.
