Great set of movies. I liked the first 2 the most. The special features included were pretty i teresting too. I enjoyed the discussion about the japanese yokai genre and got to learn more about Japanese legends with yokai.

If you like Japanese mythology, or Japanese fantasy or horror cinema, these movies are worth watching, even just from a technical level. All in all the first two films go hand in hand, while the third is more of a story grounded in reality with Yokai tacked on, and the fourth being a wildly different Yokai interpretation from another era of Japanese filmmaking. Solid box set, I enjoyed each film immensely.
