One of the most impressive movies I've ever seen.
And that says a lot for me. I'm a dvd collector with currently 800+ films in my collection and there are only a few in which I spent half the time with my mouth agape.
I thought no other korean movie could top Oldboy or Memories of murder, but I'm seriously considering Thirst to be exactly as good as both of them. The astounding cinematography and the perfect mix between Horror and Romance with the perfect amount of gore that's necessary linked with the religious theme of the movie.
I can see some minor flaws in the picture, but nothing too big to not recognize this as a masterpiece. I can't believe that there are people only giving this movie 8/10 or 9/10.
Another example for breathtakingly amazing modern korean cinema.
