Exploring almost all of Junji Ito's work by this point has made something very clear: the man has the craziest imagination for horror and absurd horror, and his art is always great nightmare fuel, but he's not the best writer. He can't always develop his ideas well or give them a good conclusion. 

So, once again, I'm saying this about one of his mangas: the idea was interesting, the art was great, but the execution wasn't good all the way through and the storytelling didn't fully grip me.
