Well I am not much of a writer n just stating my opinion of this movie. If you are a J horror addict just like me, no doubt you wil throughly enjoy this.
The story is heavily based on the urban legend or Folklore of kotoribako. If ur unaware about it u wil find abit of a difficulty understanding certain situations happening in the film. Though its ur typical curse movie, it's more than just a curse movie at the same time. Familial love n sacrifice for ur beloved also plays a role in it. Contains no Jumpscares at all but rather has more of a psychological/supernatural element to it.
Acting was good, all actors did their part very well.
Music was eerie perfect for the situation n circumstances going on in the movie.
As for re-watch value it depends on the person,horror movies are not everyone's cup of tea so if ur a horror addict who is interested in less of jumpscare n more of plot based movies then yes but if u like jump fest then no you won't enjoy this.
The cinematography n the visual effects was pretty good,certain Supernatural elements felt very realistic. Overall a very good movie.
