I never thought I'd consider abandoning anything with Park Seo Joon in it but this is dragging badly. I really should start dropping things I don't enjoy rather than hanging on to the bitter end - it's not a happy-making habit.
So my problems with it are mainly to do with the casting:
The female lead (Go Ah Ra) is doing my head in and I just can't warm to her in any way.
I also CANNOT STAND the actor Choi Won Young who plays her dad (oh my god oh my god oh my god I can't stand him). Maybe he hates the role and is trying to ham it up - who knows - but he's just cheesy and bad. I think the Queen is a great actress and he ruins her scenes.
Continuing the negativity (:-P) I have a strong dislike for Seo Yea Ji (princess). I have only seen her in this and "Save Me" but feel I have spent enough hours watching that same expression to last a lifetime.

Good bits:
Park Seo Joon - goes without saying - and Mak Moon (Lee Kwang Soo)'s bro-vibes were my favorite part of the whole thing.
First few episodes are ace
Love the soundtrack
Park Hyung Sik who I hadn't come across before and I thought his acting was great
Choi Min Ho who I hadn't come across before either. I thought he was a decent actor, has gorgeous eyes and his styling was awesome - very mortal combat
Queen (Kim Jee Soo) is great
V = cutie
V's older brother (Kim Hyun Joon) - also a cutie. I liked his scenes with the King's bodyguard pretending to be in his 20's

I think I will finish it eventually - I'll just try and skip over the scenes with the people who agitate me :-)
