As a guy I will make this review with a guys perspective. first IMO there are factors to make a romantic movie successful. 1. The guy should be likable, I should imagine myself as i am the guy in this movie I must say that I already watched jay chou in some movies and those movies makes me think that he is a bad actor. I am talking about initial D(which IMO should not exist) and green hornet. So I hesitate watching this movie because this number 1 factor I think is impossible but i was wrong it is not difficult to sink to his character and made me think he is me. Tho I think jay chou suck at one scene....the first time she and the female lead met, His reaction is overacting as f*ck. 2. I should fall in love with the girls character This #2 factor is what made me love this movie. The female lead is a simple girl that becomes really pretty when she smiles. I also like her cheerful character that appears somewhat weak. It makes me wanna protect her. 3. The setting should be realistic Now this IMO the biggest weakness of the movie. Its hard to imagine their school exist in real life. In fact at first I thought it is a harry potter music school, their uniform, characters and event that happen is harry potter-ish even the ambiance. The story at first I already get a hint that she is somewhat not part of that world. This might be because of the way they shot some scenes and she is always with the guys character...this is a give away. The concept is genius but they failed to execute it well. This concept is somewhat similar to beautiful mind starring russell crowe , where that movie execute that concept well and this movie secret didn't. The script is genius but also amateur-ish, like they didn't care about plot holes as long as the scene is dramatic...example is the chalk writing that appears in guys desk near the end of the movie. Yes that is a dramatic scene but also a huge plot hole in the movie not just a plot hole but also a somewhat misleading scene that made me think she is a ghost. Without that scene this might be a better movie. Also that ending picture at the end WTF another huge plot hole just to have a more dramatic ending. Now for the things the I like about this film Music.. "music can tell thousand stories, music can portrays different emotions" The piano battle...that scene alone makes this movie worth watching, That one hand technique by that main guy is epic he totally owned the other guy in their battle. I don't care about the songs used in this film I just don't feel the essence, Its the background music the makes this film a nice film to watch specially that music played during the first time the girl time traveled. Probably I will watch this again with my girlfriend and see what her reaction about this.
