I've wanted to watch this movie since I found out that Chun Woo Hee was going to be in it, and then the trailer came out and it was spectacular. I was curious about the director's past work, so I watched The Chaser, which I liked but didn't love, so I wasn't sure of what to expect of The Wailing. Now I've finally seen it, and the first thing that comes to my mind is WOW. The film is simply spectacular. It is one of the best films I've seen this year, maybe ever. The storyline is crazy, you never now what's going to happen. I love how it's really difficult to know what's going on and there are questions left unanswered. I was also surprised by the more supernatural aspects. Also, despite the very long runtime, I was NEVER bored, and in my opinion the movie kept the perfect pace. Now, I have to warn you: the story is disturbing, nightmarish and even dantesque. It comes REALLY close to being a horror film, and there are some pretty graphic scenes, so if you're not into that kind of stuff, be really careful. The cast is BRILLIANT. I've never seen Kwak Do Won in anything, but his performance here is great, and he really carries the film, even if his character is rather unlikable. Hwang Jeong Min is good too, but his performance is probably the weakest of all the main actors. He was much better in Veteran. I love Chun Woo Hee, and her performance is truly mesmerizing, but she's in the film less than 20 minutes (and the film is 2 and half hours long), so, even if her character is very important, I really wish she had much more screentime. Now, the real MVP of this film is Jun Kunimura. I had seen him in a few Japanese movies, but his performance his is INCREDIBLE. It's just so layered, you never really know until the very end if he is good or evil. The soundtrack is fantastic, and it really helps set the tense, chilling atmosphere of the movie. It's also really well used in the most intense moments of the story. I also need to comment on the cinematography. The film looks SO beautiful. Seriously, it's so well shot, and it fits the content and the tone of the story really well. It might just be the best cinematography I've seen in a Korean movie. Basically, the director (and also writer) did a brilliant job with every aspect of this movie. About the rewatch value, I gave it the maximum score because I believe this is kind of the film where you discover new things everytime you watch it. Despite the imposing, I plan to watch it again soon to try and understand everything better. In conclusion, The Wailing is one the best films I've seen this year (maybe in my life), and I really recommend it to everyone who's looking for something different and brilliant. But, like I said before, be ready for A LOT of darkness and disturbing content (plus the long runtime).
