The movie's strengths lie in its carefully planned narrative, evocative imagery, and strong acting—particularly Masaki Suda’s performance, which is a departure from what he has done before. The rest of the cast also does well, creating a believable and even-handed group of characters. Nevertheless, it isn’t without problems; some moments feel unrealistic, like the depictions of murders, and certain characters lack detailed backgrounds. The ending, though intended to make you think, feels incomplete because it raises questions that aren't resolved.
