I'm not sure what all the hype is over this Kdrama, but I found it to be cliche among other things. For starters, it's waaaay too long. What was done in 25 episodes could have easily fit into 12. I realize it was filmed nearly a decade ago, so perhaps what I find as faults was the trend at the time.
After watching Kdramas for many years, there are several I have watched more than once and will visit again.
However, Boys Over Flowers will not be one of them....
