nice thread...
I'm one of those Korean fanatics since 2005. Ever since then, Korean movies has been my favorite asian cinemas. I follow my favorite actress/actor, korean drama, movies, k-pop, etc. Our local station gets 24/7 Korean shows with English subtitle.
I think I have seen and own all my favorite movies and drama already.
It's very subjective as I might love something while you might find it mediocre.
My recommendation is for you to subscribe to Netflix for free the 1st month. It has tons of Korean movies and drama that you can preview for free. Check it out...
Keep in mind...A LOT of titles are still in DVD. Those are the ones that you should be watching...
FYI...most of the actors/actress start filming in Korean drama...and once they're popular, they move into movies.
Here is one that not too many people list...
Sunflower: - It's a very touching movie...the fight scene is very similar style to
A Bittersweet Life and
A Man From Nowhere.
