Sat on this movie for a long time and finally got to watching it.
There were a couple of good scares that I really enjoyed. However, this movie is mostly cheap jump-scares so if you despise those, I'd suggest you pass on this.
I also liked how the spirits/ghosts looked, although this is subjective.

There is one plothole that stuck out to me regarding May, like the other review mentioned, although this can just be chalked up to her name being written and the malevolence of the spirit Miko.

Not much rewatch value, but a decent cast with good acting. All in all, alright movie.
