I love love love Another Miss Oh :) Is Absolute Boyfriend as bad as people say it is? I heard it's pretty bad.

Yea it's pretty bad I felt. Flat story throughout with little development except a few emotional sobs. They could have wrapped it up in 4-5 episodes I felt like.

Another Miss Oh was spectacularly funny, I've not laughed as much watching any other k-drama. The actress Seo Hyun Jin was amazing playing that oddball character.

I decided to watch Another Miss Oh because it's from the same director as Marriage, Not Dating, which was amazingly funny as well. Loved the actress Han Groo in that series but she decided to quit acting shortly after that series.

Then after Another Miss Oh I immediately started watching The Beauty Inside (same director as Another Miss Oh and Marriage, Not Dating, and also same actress). It's more drama-rom focused but also comedy.

I really consider those 3 series as a some-kind-of trilogy, because they are in the same spectrum of genres and from the same director, and some of the actors are in cameo roles and there are Easter eggs hidden throughout referencing previous series. (First marriage not dating, then another miss oh and then beauty inside)

 just an obsessed fan:
Worst-
Backstreet Rookie
Heirs
Hi Bye Mama

Heirs is also overrated I agree.

But I thought Hi Bye Mama was on of the better series. However it's a series that is very emotionally challenging and perhaps not for everyone's taste buds.

Best:

Worst:

The King:  Eternal Monarch 

Hi Bye Mama

I love all three of these as well and Seo Hyun Jin is one of my favorite actresses. If she is in a drama I will probably watch it.
