Reception
Critical response
Puah Ziwei of NME rated the series 5 out of 5 stars, claiming that "this well-written Korean historical series will keep you hooked on its bloody tale of war and survival." He praised the conflict between Kang Cho and Gang Gam-chan, respectively played by Lee Won-jong and Choi Soo-jong, and the "delightfully malleable" performance of Baek Sung-hyun who played Mokjong, "an openly gay king" without any heirs. He also applauded the fact that the show depicted the times of Goryeo–Khitan War through an "old-school sageuk charm and style", and stated that "much like the anxious times it is inspired by, Korea-Khitan War is driven by purpose and complex interpersonal dynamics that leave little time for theatrics". Choi Bo-yun noted that in the series, there is a narrative of putting people first even in the midst of war, shedding light on less well-known battles and figures of Korean history such as Yang Gyu, and that the growth of King Hyeonjong who won the two wars against the Khitans with the help of Gang Gam-chan is worth watching.
Historical novel author Gil Seung-soo, who wrote the original novel which the series is based on, expressed his disappointment about the progression of the show after episode 16, since he was dissatisfied by the fact that it not only deviated from his novel, but also from actual Goryeo history. He criticized the attitude of the scriptwriter and the way he anachronistically portrayed the local gentries of early 11th century Goryeo, claiming that the series' depiction is just as absurd as "BTS suddenly appearing right after the Korean war" and that the production team should have been more careful to depict history accurately. The article noted that many viewers also complained about the storyline after episode 16, even visiting author Gil's personal blog to leave a comment about their concerns for the series.
