“Chris Brown: Welcome to My Life” (Credit: Gravitas Ventures) Singer Chris Brown’s documentary “Welcome to My Life,” released via Netflix this month, is a retelling of his rise to fame and the controversy that mired it. It seems, even by its packaging, that it’s a bid to complicate and add nuance to the unfavorable headlines and numerous courtroom dates that have defined Brown’s career as much as his music has over the last eight years. “I’m tired of giving people something to talk about,” he says at the beginning of the film.
