I like it, but I don't think people were quite ready for an oddball love story after the intensity of Park's early work. So fans and critics were a little harsher on it than it deserved.
It's probably his weakest film (along with CUT from THREE... EXTREMES) but a lesser Chan-wook Park film is still better than most other directors working at their best.
And I do like Lim Su-Jeong. She was amazing in A TALE OF TWO SISTERS.
