I love series like Natsume Yujincho, xxxHolic, Mononoke and Hozuki no Reitetsu. I first started watching this series when it originally came but dropped it cause it didn't seem to have much depth to it. I recently decided to give it a second try and to my horror, with each passing episode, I realized that i had in fact already finished the series when it originally came out - it was just SO BLAND I forgot about it completely.
So, why didn't I like it?
The main character is as 2D as they come and the author has clearly committed one of the
big writing sins of "everything the character does ends up being correct cause it all ends well in the end". It's especially frustrating when his mentor, the head of Mononokean has clearly had to suffer for his ability to see yokai and now comes along our main character and everything goes right for him.
When it comes to all the other background characters they're so stereotypical you'll feel like you've seen all of them before in some other shows.
Would I recommend it?
If you liked series like Natsume Yujincho, xxxHolic and Mononoke but wish for something more lighthearted, more mainstream, something that doesn't deal with any difficult topics in any meaningful way and has less depth story wise, this is the series for you!
