Months ago as I was looking for piano pieces, I found a video "Secret Piano Battle". A group of high school students come together watching two of their classmates competing in piano with some really difficult pieces to excel each other. That scene is taken from this movie and I finally watched it last night. First thing is I really wanted to study at a high school like this one where you can have piano battles with friends instead of bickering idly. -_- That being said, I liked all the piano scenes especially the battle scene and the"Secret". The film is a bit paranormal, there is a good twist which I wasn't expecting to happen so it did surprise me near the final.Other than music, it tells us a few things about friendship,being the "odd" one among the people, not being able to fit in... The final scene left me a bit up in the air. I can't say I didn't like it but then I can't say I did either. I just think they may have thought something better for the final scene. Still, it may worth watching once if you like music.
