I think this movie is underrated

Not sure which version I'm watching, but I think it's brilliant and worth watching, and I think it's a bit underrated right now. Several reversals made the viewers doubt their own judgment, and after watching the whole story, the details and many shots felt that they were handled well. Fragmented narrative, mixed with true and false reverse order, but I think the final story is very smooth ?

The horror scenes are well shot, there is no artificial light and background music, I was really scared ? and there is no abuse of horror?

Then my personal opinion is that the police officer is real, it cannot be the imagination of the uncle. Details: ① One version begins with the uncle walking along the railroad tracks alone trying to find and kill the police officer (the police officer is actually dead), and another version is that the prosecutor asked him why he wanted to kill the police officer. ②The old friend police listened to the recording of the police officer's harsh words to the uncle through the phone. If it is an imaginary character, there will be no "real character" intervening to assist. For example, the uncle's sister, who is not real, has never had contact with anyone other than the uncle. ③ When Bamboo Forest's body was found, the uncle was hunted down. The uncle knocked out policemen A and B who came to arrest him, and then the uncle's old friend was killed in the forest cabin. If the police officer is an imaginary person, then the old friend was killed by the uncle? The uncle has no such motive.

The police officer's story: When he was a child, his father was abusive, and his son tried to kill his father, but his mother knocked half of his head off. Serial killings by police officers mainly kill young women in their teens and twenties

Grandpa's story: My mother died of dystocia when I was born (I deduced, don't spray if I'm wrong. Because Grandpa said that he was a murderer when he was born ?) My father was drinking and domestic violence, my son killed my father, and my sister couldn't accept suicide. The son later grew up and got married and had a daughter, only to find that he was green and the daughter was not his own. Killed the adulterer and his wife. The serial murders of the uncle are mainly to kill women with heavy makeup/gorgeous manners (wife's ruby ​​necklace, dog-abuse girl with diamond ring, and out-of-control strangulation of daughter's neck that day, the fuse that went out of control was that daughter came home too late/dressed up/began to wear short make-up skirt)

Some people complain that the details of the twitching eyes are superfluous, and I think it's okay. Eye twitching is when the uncle's inner feelings and "memory" are fighting. Eye twitching doesn't happen all the time, it only happens under certain circumstances. At the beginning, the strokes were particularly powerful, and that was in reverse order. That was when the old man had severe Alzheimer's disease, so he was pumping very hard.

In the end, two hours is indeed a little longer haha, in fact, it would be better to cut it for another 20 minutes
