First of all, do not be frightened by the *low* score.. I am trying to stay objective about everything I watch nowadays, no random 10's... So, I adored the story line.. It had real character building (even though it's a movie) and all the small stories that were featured were heartbreakingly moving in a beautiful way. This is a bit of a cry movie, but in a sweet way (and you actually feel happy about crying). The acting was good, nothing to be amazed about. She did a great job, he did it a bit less (but that was due to the very tiny character building on the male lead side) but the lovely thing in this movie were all the suporting role, they made the movie sweet and fun to watch. However, for Running Man fans... get ready to grin your face off... Lee Kwang Soo has a super fun suporting role (and there are cameo's of his RM colleagues) Well, because of the important role of music in the movie (she's a radio DJ and ex-idol and all) you would expect an outstanding Original Soundtrack... That was not really the case, but if you watch the movie you'll get why I gave a 10 for music. All in all, the movie gives a good vibe and message about how people sacrifice themselves to help others and the importance of loved-ones Definitely a rewatch p.s. can be watched in any mood. Really, any mood.
