Fuan no Tane and + are both horrible in my opinion. I personally dislike the style because each mini-story is in a cookie cutter layout. I think a short story needs to at least have 20 or so pages instead of 5. An issue that I think is relatively apparent with the cookie cutter layout, is that there is not even any shock value due to the same things happening over and over again. One may say that the art is good, which it is, but it does not really fit the genre very well due to the smooth looking textures of the faces. Thisresults in a more light-hearted appearance, which contrasts to a more spooky rugged look. I also do not care much for the art style of the faces although others may think they are drawn well.

Another issue with the spooky factor is that some things just seem flat out normal and could be experienced by the average Joe misinterpreting/deluding events. I'll go with the lax example of the QR-code deleting your files. That isn't really supernatural, it is just someone being vindictive. Another example could be "Parking Lot". One could say that it is creepy because it could happen to you, but it isn't creepy because for the given example, you could just be seeing shadows (in real life it would be creepy, but not in a manga because such events are not surprising).

A vast majority of the chapters were nothing burgers and the only ones I actually enjoyed were Underpass and the last chapter of the original Fuan about the mangaka's life. But nonetheless, if you enjoy amazing things like B movies or Garzey's Wing, you won't like this manga.
