A good movie that wanted to cover too many plotlines and topics.

At first, the movie starts with an interesting topic of religious freedom and how loose laws can support the creation of various cults, which will pray on people's beliefs and convictions. Sadly, as the plot progresses and the supernatural aspects are being introduced, the initial meaning and message about the fake religious beliefs in cults makes no sense, since the investigated by the Park Woong Jae events do involve a "higher power".

Plot wise, it was just too much. Crime investigation, cults research, demonic twins, Deer Mount cult, immortality and the whole lore and background surrounding Buddhism - at least half of it should be cut off. The movie would be far better if it either was psychological thriller without supernatural elements, where Park Woong Jae works with police to uncover the truth behind the cult OR movie focused only on supernatural, without any crime connection, with Park Woong Jae, as a person with much doubt, being challenged about his beliefs as he dives into the Deer Mount cult case.

One thing that the show did extremely well was the visual aspects and (except for one scene) special effects, make up and set design. Chun Na Han's dream sequences were truly well done and beautifully shot. Even though the scenes were quite simple, they did carry the meaning behind them well - the guilt and mental struggle of Na Han.

Overall, I wasn't bored, but I did question some choices that were made. While the plot is not that hard to understand, the message is not so clear. Would recommend it as a group watch, since the movie has a few plot twists that would be entertaining to try to predict while watching with others.
