Of course I'd recommend Korean movies the most!
Korea's cultural output is best known for Korean dramas and teen idols, but I think the most praiseworthy are Korean movies, which have a completely different style from Korean dramas. Unlike Korean dramas, which try to create a mindless romantic atmosphere, Korean movies reflect more on social issues and are most eager to satirize the Korean government, haha. Korean movies actually have a wide range of subjects, but are dominated by suspense, crime and action movies, which are also the most outstanding genres in Korean cinema.
Let's start with my favorite director, Luo Hongzhen. He's better known for his movies The Chaser, Yellow Sea, and most recently, The Cry. He has won the Korean Baeksang Art Awards in the movie category, the Korean Film Daejong Award, and the 5th Asian Film Awards for Best Director for these movies. The Cry was selected for the Cannes Film Festival. All three movies are in the suspense thriller category and are very good in terms of viewing experience, with a tight and smooth plot that pulls at the heartstrings. Among them, the entry point of Huang Hai is also worth mentioning, which reflects the life of Yanbian Koreans in the cracks. And Crying, as a genre movie, is very much its own character and carries a lot of metaphors, expressing the director's many thoughts on religion and human nature without sacrificing the movie-going experience.

Another director to recommend is Park Chan-wook. He is known for his revenge trilogy, which is "I Want Revenge", "Old Boy" and "Kindly Gold". His romantic film Robot Love won the Alfred Bauer Award at the 57th Berlin International Film Festival. His most recent film, "Miss", is also about revenge, with a homoerotic twist, and is worth a look.

Bong Joon-ho's Memories of Murder, Mother, Monster of the Han River, and Train to the Snowy Kingdom are some of his best works. There are also very wonderful and ironic Korean movies like "Live Terror", "Hope", "The Tunnel", "The Melting Pot" and many more, which I won't mention here. It's worth mentioning that actor Ha Jung-woo, who starred in many of the films mentioned above, is truly an excellent actor who can handle many types of roles, such as psychopathic murderers, war heroes, and townspeople. He himself directed the movie "Xu San Guan" (yes it's an adaptation of the novel "Xu San Guan Selling Blood"), and while he's not as good as a director as he is as an actor, this one is worth watching, very interesting and good at sensationalizing.
