New World - I think this is the best gangster movie out there. I really liked it because it was cool, intense, and unpredictable.

Proof of Innocence - It was a really fun movie..good plot.

Detective K - I liked it because it was a funny movie.
Sunny - a story of 5 friends living in 1980's Korea. It's probably one of my most favourite movies of all time
Hello Ghost - a comedy with melodrama elements. Prepare tissues!!
Miss Granny - another funny movie. it was quite a hit in korea
Twenty
Train To Busan
Fabricated City
The King and the Clown
A Werewolf Boy
Miracle in Cell No. 7
The Man From Nowhere
Sunny
Thank you for the recs! I've already watched and LOVED a Werewolf Boy, Beauty Inside, Train to Busan, and Miracle in Cell No. 7.
