As much as I love Korean cinema, I will admit that they are very much a country that doesn't so much innovate, when it comes to film. They seem to be more content imitating the output of other countries. There are some notable exceptions, in particular the works of Kim Jee-Woon, which are wholly original and are spawning imitators in other countries, both in Asia, and the Americas. However, the country is more known for its lack of creative output and general production of cinema which favours style over substance. Say Yes is certainly not original, and is obviously inspired by a number of American thrillers from the past decade. The similarities are glaring, making it hard to dismiss the film as anything more than a cheap imitation of films which needn't be imitated. For some reason, however, I enjoyed it.
Celebrating their one year anniversary, a couple travels across the east coast of Korea. After they back into a man with their car, they figure the least they can do is give him a lift wherever he's going. After threatening their lives, they kick him out of their vehicle. Lo and behold, he seems to be following them along the coast terrorizing them along the way. I won't divulge any more information than that, however, upon watching the film you will realize the wealth of films from which Say Yes borrows its content.
A big reason for my enjoyment of the film is the inclusion of Joong-Hoon Park. The man is the near-personification of cool (Chow Yun-Fat is THE personification of cool). He injects every role with an incredible intensity, and he can do this with a single sneer of his lip. He is more than capable of believably filling the role of hero or villain. See Nowhere to Hide for another example of his intensity in front of the camera. Although his performance in Say Yes is definitely over the top, the film is no less enjoyable because of it.
Say Yes also produces a number of cringe-worthy sequences of violence and a climax which boasts an incredible amount of blood. There's not a lot of violence throughout the first half of the film, but by the time the film reaches its climax, the blood is literally flying. Broken fingers, severed heads, throats slit, and even more broken fingers… it's an enjoyable time.
While the killer's motives are kept secret throughout the film, he reveals the reason behind his actions to our protagonist. I must say, you're going to have to give us a little more than that folks. His reasoning is hardly a credible reason for him to do the things he did while terrorizing this couple. It definitely reduces the credibility of a script which really didn't have much to begin with.
While completely unoriginal, something about Say Yes is appealing. It must have something to do with the sensibility toward stylish direction which Korea is best known for. I can't put my finger on it. While I can't give the film a recommendation simply based on the fact that I moderately enjoyed it regardless of its many weaknesses, I can suggest that fans of American thrillers such as Seven, The Vanishing, and the like may enjoy it more than those of us who've seen the potential of films being produced overseas. For us, Say Yes is a substantial let-down.
