The overall feel of Natsume Yuujinchou always leaves you satisfied after an episode. It has some type of charm about it, as well as Natsume himself. The relationship he has with the demons as well as Madara (Nyanko) is what really made me enjoy. I always love animes that have good chemistry amongst themselves, as well as having substance.
It's a really good watch and unless you absolutely need non stop action then you will enjoy Natsume Yuujinchou.
