It's between Volver (Pedro Almodovar) and 3-iron (Kim-Ki Duk).

Only seen them once. I will see Volver somewhere in the future, but I'm unlikely to see 3-iron again unless it was screened somewhere (which is a possibility as I'm lucky to be in a city with numerous old movies showings). I feel like it requires to be exactly in the right mood for it and I don't want to spoil my memory of it.
