I have seen this when years back, while my friends were hooked with it, I remember not liking it as I thought I would at that time.
I watched it again today to find out why I it was a so so movie for me before and checked if it will give me different feelings now.
Well, It's a good movie, but not a great one. It is still so so for me. Maybe because my expectations from a movie is the same as what Kdramas make me feel but for some reasons I just didn't feel that from watching this.
