Thanks for the heads up JB!

The cast feels weird to me for some reason. Gonna check it out just to see Cha Seung Won and Lee Sung Min.

I guess it is fan pressure or something.
He really hasn´t impressed me much.
but I am going to have to watch this for Cha Seung Won.

He's one of those actors that I can never understand how they got an overnight shot to fame.

Aw man. For a second I read this as Park Seo-joon and got super excited. But SKJ is really... meh. Not a great actor by a long stretch, and he pretty much has zero personality in real life if Roommate is anything to go by.

He also really rubs me the wrong way after his role in What's With This Family. I realize it's not his fault that he plays a creepy, obsessive guy with no boundaries, but since he was like that in Sly too, it's only reinforcing the impression. (Plus his face weirds me out, but I try not to care, because that's unfair.)

It's unfortunate because the rest of the cast is so amazeballs. But then, we've said similar things about Lee Yeon-hee in the past, and look at her now! So there's always hope I guess.

He's also in an idol group (5urprise), if that helps to explain anything?

This guy's beauty is phenomenol. I used to think he was coasting as well but in What's with this family? he did this crying scene that just almost broke my heart. I think he has it in him to be really good. Not sure I'm liking the idea of making Prince Gwanghae a big bad but hey this is dramaland...all about flipping those royal tropes. Thanks for the news.

Cha Seung-won and Lee Yeon-hee. I feel a really strong spark!
And now Seo Kang-joon in the mix? That's crazily adorable!
I will not miss this at any cost.

(Speaking of sageuk, I regret watching MAIDS without an Episode 2. IT IS REALLY TOO FREAKING GOOD!!! I am soooooooo devastated! I am really sad about the loss, and I understand the grief right now. I extend my comfort to them. Maids is really too good to be true, right now.)

I will say Seo Kang Joon is very cute, but honestly, between my Cha Seung Won and Lee Sung Min ahjussi, I won't really care much about whoever he plays.

Kang Joon is popular because he's pretty. I watched him on Roommate last season and this season. He isn't too bright, and doesn't have much of a personality yet all the women get stupid over him. Last season his popularity turned the other kid on the show, Park Min woo into a wreck. Even though he was smarter and more accomplished, taller (which is a big deal in Korea) and good looking evidently he's just not considered as good looking as Kang Joon. This is a perfect example of a shallow business that considers looks a priority over everything else, because Kang Joon is so quiet and reserved he doesn't seem to have much charm or personality at all. I'm willing to watch him in a lead roles so I can see if he's one of those people that wakes up when they are performing.

Is he that popular in Korea? Really? Or does he belong to a powerful agency that's short of actors in his age group?

At any rate, he makes more of an impression than the likes of Ahn Jae-hyun, and as someone pointed out, the true male lead of this drama will be Cha Seung-won.

His acting isn't great, but it's not bad either - he has great chemistry with Nam Ji-hyun in What's With This Family, but Park Hyung-shik out-acts him easily. Except in scenes with his 'byuntae hyungnim', those are hilarious.

And JB you've given passes to actors who are far worse than him, I'll keep an open mind and hope he doesn't butcher his sageuk speech.

I don't want "Pride and Prejudice to end T.T

I think the problem with this for me...is just that there are SO MANY actors I'd rather see in lead roles, some that I've been literally waiting for...for years. And then him and Ahn Jae-hyun just kind of swoop in...ah, well. I'll give them the chance to prove me wrong.

I have a huge soft spot for Seo Kang-joon since After School: Lucky or Not Club which was light, funny and adorable, and he was okay in. But mostly, I like him because of Roommates, because he seemed so real and genuine and sweet in it. Do I think he's ready for a leading role? No. I don't. I think, maybe in a few years, he could be, but now? No. I'm sorry, but I seriously don't think he can hold up against Cha Seung-won or Lee Sung-min. I hope he will, but I don't think he will. I'll be looking forward to this, though, and I hope I'm proven wrong. Seo Kang-joon, fighting!

Well...I like Seo Kang Joon. Charming guy. Makes me smile/laugh in the performances I've seen. He'll either get better or he won't. There are actors who I've started out loving but now can't stand, so e's OK in my book.

I would love to finish a saeguk drama one day. Each one I start, I give up on down the road. Maybe I'll keep an eye on this. I like who is involved + want to see if Lee Yeon He can keep up with what she brought in Miss Korea.

Well I've seen him in this drama special on mbc and he's quite good in that. Infact he's got a lot of praise for it and his name became a searching trend on daum and naver right after the airing. I think its called Haneuljae's Murder if anyone's wondering. The plot is weird and taboo-ish but yeah its like a typical indie film. Lol

I don't find him attractive, more like striking but in sort of a scary way. Because of that, all I see is less than mediocre actor but he could get good with time and practice.

It seems because his looks have been so well received he's moving up more quickly than usual and it's not fair in a way but it happens. Hope he steps up and uses his new opportunities to really hone his acting skills and get better.
