The only one I'm unsure of is Biscuit Teacher and Star Candy. Personally, I really enjoyed it. Gong Yoo is a fantastic actor though, so sometimes I'm not sure if it's amazing or if it's just him making it seem amazing. Then again, Big was a total bomb, so maybe BTaSC is underrated. Lol.
The Vineyard Man, it is one of my favorites. Maybe people don't care to watch it because of the rural setting, but I loved it.
Yes I totally agree with you, Prosecutor Princess is much underrated. I love the ways In-Woo take good care Hye-Ri. After watching this, Park Si-Soo ranks my number one actor.

You're Beautiful is overrated in my opinion.
These shows haven't gotten the attention they deserve:
The Queen's Classroom - My no.1 no one can shake its place
Little Girl K - Best action/thriller
The King of Dramas - Great
Operation Proposal - Don't understand why people hate it.
Legal High - Funniest

Dramas aren't worth hype:
The Bridal Mask - Most overrated...it's 50/50
Faith - Most overrated
Innocent Man - Was good but...
IRIS - There is my favorite actor and I love action still ultimate boredom...
Missing You - 10/10 start but after that its a (-10)
Boys Before Flower - Most overrated, I almost stopped watching K shows because of this
Under-Rated:
Ima Ai Ni Yukimasu
Legal High
ATARU
Five Fingers

Over-Rated:
