First, if you are under the age of 16, do NOT watch this movie. Due to numerous shocking scenes, this is not a movie that should be seen by a younger audience. I know that a lot of you might want to watch this movie because you really liked Gong Yoo's acting in previous dramas, but if you are 15 or younger, this movie might have a greater impact on you than you might think. You've been warned. Such a movie is impossible to rate. It's really hard to make the difference between the true story that captivates and shocks us, and the form, the way it is told, the movie. Personnally, on my MDL list, it is still rated N/A. Story...well there is no story, those are facts. Those facts are, of course, adapted and the way this movie deliver that adaptation to us is outstanding. The dark atmosphere, the suspens that keeps us on edge, and the flashbacks system that makes things so vivid, everything is done to captivate the audience. Thanks to all the members of the cast (who did an amazing job portraying their characters, especially the children and Gong Yoo...well Gong Yoo was simply exceptional) you will be trapped into this movie from its very first minute to the last. You will feel horror and despair as well little pieces of moved joy as you see the events happening as if you were there. The music isn't a beautiful melody designed to make you cry every times you hear it, but it will make you feel calm, tense, or angry. It's really a part of the movie. Rewatch value...honestly, it would be torture to me to rewatch this, but I'll still do it, because this movie is amazing and the acting astonishing. But I won't say it was beautiful. Although this movie is a piece of art, I'd feel sick to call it beautiful. Since he got the main part, let's talk about Gong Yoo in this movie. His Kang In Ho is true, sincere, so kind and pure in front of all the horror happening before his eyes that it is impossible not to be moved by him. Gong Woo is definitly a top actor and I can't wait to see what he will do next. But there is something bothering me about this movie, like all movies involving young actors.Even though this is all acting, I wonder how those children felt, when they were shooting some scenes...sometimes, I felt this movie was going too far...but this is only my point of view... I know that my review is a little dark, but I just saw Crucible, and this movie is dark.
