That's kind of how I feel -- also about LTROI, even Girl with the Dragon Tattoo (although I would drink the Rooney sisters' bath water.)
I have seen Sympathy for Mr. Vengeance, which was superb, but not Lady Vengeance. I really want to see Snowpiercer.
When I lived in Seoul my (Korean) girlfriend went to the same university as Park did, Sogang. Her all-time favorite movie was My Sassy Girl (which, if you have the time ... is pretty forward for South Korea circa 2001 ... but very much a RomCom) and I believe Park worked on that film as well.
Snowpiercer looks great, and I'm a fan of Bong Joon-ho's two preceding films (
The Host, starring the immensely talented
Song Kang-ho*, and
Mother); that Park Chan-wook is producing just adds to the intrigue.
Definitely check out
Lady Vengeance, which I think I may prefer to
Mr Vengeance (although I've only watched those two once, unlike
Oldboy) and which nicely rounds out this loose "trilogy." Meanwhile:
Thirst, I think, is the second-best film Park has directed, after
Oldboy;
his US debut,
Stoker, was solid though unamazing.
I haven't seen, nor had I heard of,
My Sassy Girl, but I'll give it a look sometime soon. I also suspect we may have been introduced to SK cinema by similar vectors.

Song Kang-ho also has a tremendous turn in this really ****ing great film.
