This review will cover all seasons of 'Natsume Yuujinchou' following the first and not just the fourth. although these series extended on the first season, there was no notable drop in quality.

Each season seemed to have a different perspective which was also reflected in the opening. One was more about exorcists. Another about friendship and schoollife and the last leaned more toward the family aspect. Though the stories differ a bit, the characters don't. Their motivations stay the same but the events change their actions.

A few new characters were added and old ones appeared again. There were no real changes in the relationships between them though so the conversations stayed more or less the same.

If it wasn't for the recaps at the start of each new season you could watch all episodes of 'Natsume Yuujinchou' and barely even notice that there are separate seasons. Fitting its calmness this show seems unchanging and is still perfect if you want to relax.

What I liked:
- Doesn't stray from its original focus
- Soothing art and music
- The few new characters are a good addition


What I didn't like:
- Reiko is still shrouded in mystery
- Some recurring themes (love between human and spirit, protecting family)
- Some characters didn't appear as much as I would like (show less)
