I gave it a 2 because it was too violent for me. I clicked the +10 seconds button a lot when it got too gory.
Also, I was bummed at the unfinished ending and wanted a part 2 immediately.
Sorry, I always make my ratings personal, lol.

Loved:
*loved the cast. the acting was perfection. Kim Da Mi is perfection
*loved the story's pacing; it was slow but never felt slow
*loved the dark filming aesthetic... randomly gave me BTS Mic Drop Aoki remix MV vibes? lol...
*loved her quiet relationship with her adopted parents and with the townspeople
*loved the subtle reveals at the end that actually did surprise me (when you find out what different characters actually knew)

Saddened:
*the story was too sad and violent
*so much blood... like, so so so much blood
*so much violence... cringe amount for me... i know, i know, it has a mature rating, i should have expected it... i only watched this movie because i saw a pretty fan edit on youtube, so it's my bad. but i'm being honest here, movies don't need to be that violent! let's just all chill out. let's stop making them so violent. plez.
*they killed Choi Woo Shik? I don't believe it. Don't kill his curly head. i don't think he's dead. i know he's probably dead, but i'm a sucker for redemptions. let's make him not dead and give all the character redemption arcs.
*the ending was cliffhanger? now i have to live on knowing she's still out there somewhere trying to find her peace? No! give her peace! give me peace! give all of them peace! it can be quiet and broken, but make it peaceful!
*ugh, this is what happens when i stray into the mature side of film making. sure, this was a masterpiece, but now i'm sad, so i gotta scurry back to the safety of my own favorite genres that have less violence and less heartbreak... until the second movie comes out. then i'll probably watch that one too, and skip all the violent scenes of that too, just so i can see if Goo Ja Yun gets a happy ending... what can I say, I just always like Kim Da Mi's characters and wish them well.
