Nice Spoiler!

I feel the other way around. LBH not good, but JJH very good. LBH always have tears in his eyes each time he wants to show some emotion but I just don't feel for his character. He tried too hard it becomes unnatural. On the other hand, JJH as Sa Woo makes me hate him. So he succeed and did a great job being the antagonist. KTH just an eye candy in this drama.

KSY+KSW are the best,excellent in IRIS..although they are supporting casts but their performance just outshone the leading casts such as LBH,JJH+KTH!!!

It is such the stupid report from stupid reporter.
This report does not worth a cent because it just shows the bias of some audiences. Audiences who saw KTH in drama “stairway to Heaven” has big bias on her & put unreasoned stricter standards on her. In “stairway to Heaven”, director assigned KTH the role of “the bad sister, the evil”. Audiences hate the role of bad sister & translate to they hate KTH. It is the confusion of some audiences.
Audiences hate the role of “bad sister” a lot, so it proves KTH plays the role of “bad sister” well & successfully makes audiences dislike the role of “the evil, the bad sister”. It is exactly what director wants. So, KTH acts well.

3) The fact, audicences had big prejudice on KTH since seeing her on drama “stairway to Heaven”, so later, they criticize her for anything she did regardless what she did was great.

4) It is stupid to believe everything on the newspaper, internet. It is stupid to follow the unreasoned judgment of other people.

5) I am from USA, well developed country. Regardless of what you say, I believe what I saw on drama IRIS. Asian Americans here like KTH’s acting & beauty.
In IRIS, Kim Tae Hee acts excellent, far more better than kim so yeon.
LBH, Kim Tae Hee is THE BEST Korean actor & actress so far.

6) I agree with some comments in other webpages about issue "audiences have prejudice about KTH", so I copy some sentences, so I do not have to type. Sorry, I am lazy.

"Scorecard: How did IRIS’s stars measure up?". This article is just the garbage. This webpage posts it here to have many visits from fans of Iris. Fans have different opinions & post more opinions, this webpage will have more visits & they like it.
My opinion: Iris team works hard & results in the success of IRIS.
Kim Tae Hee & Lee Byung Heon is such the great couple in IRIS. Great job.
Perhaps, the more men admire Kim Tae Hee & comment that she has good acting skill, the more women criticize her. Megan Fox has the same situation.

La verdad no se que decir, estoy probando si saldra el comentario o no. Soy vietnamita y me encanta esta serie.

TOP's a bad actor. He's not convincing at all, but his good looks give him a boost I guess.

Kim So-yeon and LBH- Her love for LBH appeared to be deeper and more honest then Kim Ta-Hee's. With Kim Ta Hee one never knew where she stood. She seemed to be a person with a lot of secrets, and it was set up that way from the beginning when she scouted LBH for the organization. I felt like she had a double agenda all along, but the viewers were not privy to her inner thinking. ONe had to deduce from her actions. I felt the same way about Jun Jun-Ho who also had a secret agenda and was less forthcoming about his ambitions and who he was. He also operated on two levels, and I believe that he had a competitive drive that overshadow LBH and their friendship. Because there was no dis-simulation with LBH, in other words, he honestly spoke and acted from his heart and feelings and like an open book, though KTH and JJH were polar opposite from him. In all aspects, I felt like Kim So-yeon was more of a soul-mate to LBH, but he couldn't see that because he was blinded by his so called feelings for Kim Ta-Hee. KSY had a depth of loyalty and she was deep like a river which was a perfect off-set to LBH. Once she committed her heart, it was committed. There would have more depth for LBH and KSY in a love relationship if the plot had gone that way and much more intensity. Park Chul Yong ? over-looked that aspect and did not see her as a woman, which was unfortunate for him. I think at the end... he realized that he valued her more and saw her as a woman instead of a machine. I also believe that one of the mysteries is the KTH father is the founder of IRIS. Sau's betrayal of LBH was unexplainable. They needed to shed more light on his ambitions and his ambition to out-class LBH on everything. I enjoyed IRIS although the end is rather idiotic. I hope that even if LBH doesn't come back the second season... they will resurrect him in season three with So -Yeon.

I enjoyed the whole series but always felt it could have been better. I totally agreed that TOP's image fitted the character. Oh well....let's see his next show.

@MICKEY
I think the only one bias here is you.. what you see is the beauty on the outside but no the talent.. KTH maybe more famous than KSY at the moment but it is changing rapidly nw... and there are thousand and probably had increase to millions now that confirmed and appreciate KSY acting is better than KTH. So please respect KSY as an actor.
And I don't care where you come from. so just keep quiet about criticizing KSY as an actress.

i agree LBH is A list korean actor for me ! but i think TOP was pretty good too..im a little biased but he completely convinced me! However, he did still have a sort of idol-boy feel haha

Kim Tae Hee's acting is really GOOD. I like it.

LBH is great!

KSY looks old & boring & her acting is dull. KSY's acting is monotone. She looks down almost all drama as if there is only 1 way to portray her character.

TOP, JJH is ok

KSW is BAD. His action is clumsy & slow.

So totally agree with these cards. Lee Byung Hoon and Kim So Yeon rock!!

Agreed with most of you, I don't like TOP's act in IRIS. He is cool, but I don't know, there's just something wrong when he talks.
I love Kim Seung Woo, Kim So-Yeon, and Lee Byung-heon! They did such a great job! Oh, I love Seung Woo ahjussi so much, he really did a great job every time he act.
For Kim Tae Hee's acting.... umm.. I just don't like it. She is not suitable in action drama.
But overall, this is a worth-watching drama!
