DongA Ilbo asked 10 experts, including pop culture critics, acting specialists, and broadcasting officials, to rate the acting skills of the lead actors/actresses in the 3 sageuks that are currently broadcasting. And this is the score they gave SeungGi:
The experts seemed to share the same opinion in regard to SeungGi’s acting, and said, “He has the fundamental skills, and he’s acting well without any major flaws.”
Successful even with transformation as a male gumiho
Lee Seung Gi, Sageuk UmChinAh
Strength: prominence of matching well with any roles
Weakness: ‘Heodang’ image in variety

Everything Lee Seung Gi 
Is being Heodang a weakness?? Nah! not with uri Seung Gi his heodangness is so adorable. 😀
lol whats that have to do with his acting, am I missing something?
I guess what “specialists” mean is that being heodang could make some viewers not taking his drama role seriously, which is so lame. He might be “forever heodang” in Korean people’s minds. I don’t even know if that’s a good thing or bad thing @_@
Being Hoedang is what makes him human, since he’s so perfect. Although his Hoedangness always makes hum more adorkable, adorable, funny, and makes us loves him more.
I think his Hoedangness is enviable among K -E Star, they all know that even his hoedangness sell in Variety World.
Well…everything in him is saleable, even his adorable cute flaw…
Oh please, only 80 points? Lee Seung Gi deserves at least 95 points! His heodangness makes him more interesting among other celebrities as we all know he is super intelligent n eloquent. I love the occasional heodangness as it reminded me that Seung Gi is human after all! Besides, his heodangness is so cute n adorable – brings so much laughters to the audiences. Really miss Seung Gi on variety shows……
