The story is very genuine, and if you're really into history I guess you'll fairly enjoy this movie. I have to be honest, I primarily just watched this movie because Siwon played in it (although I'm quite into history too). All in all, I think it really was a nice movie. I like the story and it isn't that hard to follow. The acting was very good, especially Andy Lau quite surprised me with his acting skills (I didn't know much about him, but he really is a great actor I have to say). On top of that, Siwon also did a great job here even though he really was a rookie in acting back then. I gave the rewatch value a 3 because I think that once you've seen it, there really is no need to watch it again. Overall I gave a Battle of Wits a 7, mainly because of the great acting and the very well executed plot. I recommend this for people who are into ancient battles and for people who just want to see Siwon in his awesome long-haired glory.
