Alright, I just watched through the movie several hours ago, and it touched me a lot.
Actually, I didn't like it at the very beginning since its dark color and "messy" scenes. Various students in the New York High School and they're taking those "weird" classes. However, they gave audiences an amazing show in the graduation ceremony with their confident faces, voices, dancing and performances. I did appreciate the processes they were trying to find their true dreams, the definitions of fame, and the values of successes and happiness. As the song they sung in the end, "cannot see behind you, you have to look ahead," and "hold your dreams, don't never let it go. Be yourself, and let the world take look at you. You'll find strength when people bring you down. They will see if you were only only believe."
Well, what is success? -- "success is waking up in the morning, so exciting about what you have to do; and you literally fly out the door, is getting to work with the people you love. Success is connecting with the world, and making people feel. It is finding a way to bond together people who have nothing in common but dream. Falling sleep in nights, you did the best job you could. Success is joy, freedom and friendship, and success is LOVE!" I did love the definition for the success. It is perfect, isn't it?!
