Well, Well, Well... I didn't expect this film to be that good after reading the synopsis, but I was pleasantly surprised. Considering that this was one of the first films the young actors had played in their acting was spot on. With this kind of film it could be easy for them to go over the top and become unlikeable horrible teenagers but I found them relatable and more importantly likeable.

The storyline was good, it had be guessing at the murderer all the way through and wasn't obvious. The film was just right in length, short enough to keep the thrills up and long enough to tell the story without confusion.

Watch this if you love a good mystery but with a bit of comedy and doesn't take itself too seriously.

I watched this movie, because I read an interview of Yoo Seung Ho where he says that he doesn't think he was that good of an actor when he was younger (LOL Younger, when he is only 20 now). Anyway, I decided to go back a few years and check out his acting for myself.

I thought that Yoo Seung Ho and Kang So Ra were really good. I have a soft spot for Kang So Ra anyway and I was pleasantly surprised to find her in this movie. The story is fairly simple and suspenseful. I love Kang So Ra's character Da Jeong. I like when the female lead is smart.

I think that most people would enjoy this movie.
