The film is interesting, but that's about it. The first hour was really slow, the whole class thing seemed quite familiar. I'm not sure why people are falling over themselves about this film, maybe since it was Korean yet with an accessible story and familiar film language that it suddenly moved westerners to 'see the light'? Anyway, the second half twists and turns struck me more as a wacky story line I would have seen on a soap opera back in the day like Young and the Restless or Days of our Lives. Overall, I'm more critical of the critics than of the film. I recommend seeing this, it's worth a look but all the Oscars and 'best film of the decade' stuff is incomprehensible.
