I don't think this was nearly as bad as all the scathing reviews are making it out to be at all. There was a really interesting story here with solid spook factor that got a little muddied by maybe a bit too much going on.
The sequence of events throughout this story were a little bumpy. It generally felt disjointed and there wasn't much finesses when attempting to weave a smooth story with cohesive transitions. It was very much that kind of movie that confuses you to then explain itself later for that "ah ha" moment. I think some of the confusion could also be bits and pieces getting lost in translation.
Regardless of this I really did enjoy this movie for what it was, granted I am a bit biased towards Indonesian horror. They made it successfully creepy and atmospheric with an engaging story. I think it would have bennifited from a bit more focus, editing and a shorter run time but it was for sure a solid watch. 6.5 rounding to a 6. Would recommend.
