Not sure about this one. There are some issues with the execution as the idea could make for a good horror movie. Perhaps the makeup of what is depicted as "ghosts" is not really convincing, up to the point that for example the "ghost" in a scene moved and looked like a zombie instead. Missed opportunity.

Like the ghost of a pretzel clock: this looked good but the innumerable WTFs, the predictable twists and the ridiculous time lines made this ghost story pale in comparison to other Asian horror.

It's a good movie, good jump scaries and plot twist. It isn't the best horror movie, but...
