We need to accept the fact that romantic comedy hit 'My Sassy Girl' (2001) popularized the 'weak male strong female' genre in South Korea. Jeon Ji-hyun is one of the most expressive and versatile South Korean artistes. However, 'Oh! Happy Day' seems like a weak clone of the original successful formula.
The ending of this film contains a string of childish slapstick scenes. The characters start to dance, sing illogically and engage in celebrations. I strongly urge fans of Jang Nara to rate this film carefully and slowly.
Mao points: 4/10
