It took me from start to finish about 3 months to complete this film. It is a mystery to me why it's called 'Rules of Dating' when in fact it has very little to do with dating. It tells the story of two teachers: a rather selfish and unscrupulous man who is also a liar and a cheat; and an emotionally unstable woman with such low self-esteem & clear mental issues it's a wonder she didn't off herself during the course of the show. With a pair of damaged, rather unlikable protagonists it doesn't take a rocket scientist to predict the train wreck of a relationship that is about to culminate between them. Unlike the Japanese movie, Happily Ever After, where you meet equally tragic individuals trying to figure out the meaning of life & love in a poignant, slightly hopeless, but always heartwarming journey, you'll struggle to understand why the heck Choi Hung & Lee Yoo Rim in Rules of Dating are together because they clearly shouldn't be. It's a very co-dependent, unhealthy, immature relationship between two people who literally have NO redeeming qualities. The acting inspired very little empathy or faith that these characters will grow into better people. Overall the plot and overarching story seemed very ill-conceived, as if the film's only purpose is to say the world is filled with some pretty strange effers. If like me you weren't born yesterday, and thus already knew this, this movie offers nothing in the way of an engaging plot, likable leads or a memorable ending. In fact when it ends you'll just be glad it did, if only so you'll never have to see these weird ass people again. Music - what music? Rewatch value: 0
