“Scrapbook” (aka “The Piano Player”) is the story of a high school sophomore desperately searching for a meaningful connection with another human being; the efforts of his popular older brother to help him out only end up making things worse, leading to a cold war between the brothers that spirals out of control when our hero falls in with the wrong crowd. A coming of age tale populated with memorable characters that takes many unpredictable twists and turns, “Scrapbook” celebrates youth in its complex blend of joy and agony — and mourns the tragic mistakes that reverberate into adulthood.
