I'm surprised no one has mentioned Gu Family Book yet. I found the pacing and story-line to be incredible. The end of every episode had a cliffhanger that just made you want to watch the next episode. A lot of times with Korean dramas the acting seems to flip flop. It's like one scene the actor really seems to be in love with the character and the next scene they're acting really cold. However I didn't experience this problem with Gu Family Book. The love was slow and budding but if really felt genuine, and the crying scenes were riveting. When they cried it wasn't a pretty pose for the camera one tear style cry. I could feel their pain, it made me cry. The plot was excellent. It's about a boy who is half kumiho who struggles to find out about his real family while trying to protect the one that raised him. The special effects were also semi-believable. Asian supernatural dramas tend to throw in special effects that are really cheesy super fake looking. But this drama kept the special effects to a minimum(using blue lights at the most). The ending is bittersweet but it's a must see in my book. Also seconding My Love From Another Star, the acting gets kinda annoying(it flip flops) but it's a solid drama with a nice plot. The ending could use some work though, you'll find out why when(if?) you watch it.
