Although the first half was some slow paced, the second half of the movie got motion & was overall capturing . Ahn-OK-yun (Jun Ji-Hyun), her small team for assassination mission & Captain Yem (Lee Jung Jae) seemed to be main characters of the plot line in the first place.But then, gradually Hawaii Pistol (Ha Jung-woo) & his sidekick Old Man (Oh Dal-su) got involved , geared up an entertainment show . By the mean time, the plot also developed some momentum to be intrigued. CGI effect,action scenes & the ancient background was so believable & realistic for this movie- so was the acting.By the ending, the movie got some symbolic meaning too.Although it could be a little more jam-packed, more artistic till the last to be memorable & greatly appreciated , Kudos to the director Choi-dong hoon - for accomplishing much improvement from his previous hit- heist movie "The Thieves" (particularly in emotion rendering section).
So if you wanna check the outcome of some tremendous efforts from director & actors to set up an epic, historical drama film based on true event - independence of Korea, it will be worth watching obviously.
My Rating: Somewhere between 7 & 8 . :)
P.S: By watching this movie,completed checking all IMDb enlisted drama-movies of "Sassy girl" Jun Ji-Hyun so far. From TV drama "Happy Together (1999)" to "Assassination (2015)" - there's a daring & frequent transformation from innocent/romantic heroine to hardcore action lady.She's lucky enough so far to receive such co-operative support from directors & co-actors + appraisal from audience along with her ambitious consistency!
