Wow, I didn't think it would be this good! Before I get into the goodies, let me preface this by saying I haven't seen the Korean movie Blind that this is apparently based off of and I'd never heard of it before watching this movie (and I finished it a minute ago); however, I definitely plan on seeing the Korean version soon! Story (9.5): Okay, hardly any story can be completely perfect and while this had its flaws more notably in police work and back story, I didn't hardly notice anything while watching. And I'm not talking major police work flaws--they were actually refreshingly intelligent after coming from K-Dramas--or flaws in the MC back story. I felt that her back story was done very well and wrapped up pretty nicely. I've heard others saying that this movie wasn't closed off quite as well as Blind, and while I'll have to watch Blind to see (haha) for myself, I didn't think this ended all that badly. Frankly, I was really glad they didn't throw in any romance like some movies might try. This movie had plenty going on without romance and I'm not watching a movie called The Witness because I want to see some people locking lips. Praise the heavens. Plus from me. Acting/Cast (9.0): All the main actors were very good, though there was one part I felt the MC was a bit stale; other than that almost all the supporting actors were top notch and props to the dog! The dog was a very good actor :) I don't really have much more to say on this other than that the antagonist was pretty good, but I've definitely seen better acting for this type of role in my Asian drama wanderings. Music (9.0): I'm basing this off the fact the music buoyed the story very well and the songs (i.e. music with words) were good. Normally I wouldn't rate this high on music unless it was something I loved and would download and listen to frequently, but I couldn't pass up a 9 when I saw that the band musicians were ACTUALLY SEMI PLAYING THE RIGHT NOTES OMG. No faked musicians here. Thank you so much. Every true musician cringes when they see fake musicians on screen. Rewatch Value (10.0): I would watch this again. I'm going to watch Blind no question. After that I might watch it with a friend. Nothing I'll watch over and over and over again, but then there isn't a single thing out there that I would. It's very hard for movies to get a 10 on rewatch from me because there's so little content compared to a drama and I get bored of stuff pretty easily if it's repetitive. Overall (9.5): Rounding up a bit, I'll total as 9.5. There weren't any parts I felt cringey on or were poorly setup. The flow and cinematography were all amazing and packed together with a fast paced horror/mystery/detective story... I was very surprised by how much I liked this. Highly recommended.
