3.5 stars only, the explanation and the outcome of 'the curse' and the deadly urban legend about a creepy cursed doll sound reasonable enough but it isn't as good as how those other masters of Japanese style of horror could have done with a similar storyline.
PS: it's interesting to see The Ring getting a lot of mentioned in the story.
PSS: I will keep an eye on author Ichi Sawamura from now on.
