Some of the dramas people have listed as overrated makes me sad :(
Underrated
KPOP The Ultimate Audition (Don't get me wrong, this is by no means a fantastic drama, but I think it gets a lot of crap from people, while still being enjoyable enough to watch.)
Haeundae Lovers (This drama was seriously fun to watch, even if it isn't the best or most believable.)
Overrated
Flower Boy Ramyun Shop
Playful Kiss
