This movie is a slow burn but well worth your time if you're in the mood for a contemplative and haunting experience.
There's a lot going on here and I won't give anything away, but suffice it to say there's a lot about guilt, duty, regret, family, and other universal human concerns here.
Don't expect gaping-faced ghosts and jump scares, this isn't that kind of film. This film is about the haunting that comes from what we do in life, how it reverberates, and whether, in the religion/spirituality of the film, those reverberations affect us and others in other lives.
You won't necessarily be scared, but if you give it a chance you might just be haunted by what the film reveals as it unfolds. The acting is great, and the lead actor is superb in the way he has a face that seems to elicit sympathy but also has a mystery to it, leaving the viewer wondering who he is deep inside. As the film progresses that question gets more and more difficult to answer.
My favourite part of the film was the recurring motif of walking a road. Will we ever find peace, or are we doomed to walk the same road for all of eternity?
One line will stay with me, when one character asks another about a ghost and where he seems to disappear to. - "I don't know where he goes." - Do any of us know where we go?
