Japanator's Chris Walden writes, "The fourth season of Natsume Yuujinchou, the popular show about a boy who keeps a book of friends instead of joining Facebook has finally come to an end. As I mentioned back in the first impressions, you should really head over to Crunchyroll and check out this series if you haven't.
But that's certainly not a review of this season in particular. I am very fond of the previous three, but does the fourth iteration overstay its welcome? Well, you'll just have to find out after the jump!"
