Tamra the Island - I hate that this one gets bad reviews. Yes the first episode makes you think WTH am I watching. But once you get past that it's truly a beautiful story. Just be sure to watch the full 21 episode version and not the awful cut version the network aired.
Dal Ja's Spring - I've actually seen this on several favorite lists. But I still its very underrated and I actually enjoyed it more than My Name Is Kim Sam Soon.
That Fool
The Vineyard Man
Last Scandal
Some dramas are not underrated: they are simply impossible to watch! Either the video has been deleted for some copyrights infringment, or the mirror is not available in half of the world countries (<- it annoys me so much, I don't even want to start), or there are no subs. :P
At the end of the day, some of us end up watching the most popular dramas because they are easy to find online.
I have Once upon a time on my to watch list, it really sounds great, but I'll have to download it if I want a chance. :(
