The new animated Lego movie, "Piece by Piece," is a documentary produced by Pharrell Williams and follows his rise to fame. Parents beware: despite the kid-friendly animation and musical elements, the documentary structure might be unexciting for younger audiences. “Piece by Piece” is an animated highlight reel of Williams’ rise to industry prowess, using his greatest hits as the soundtrack. He goes from being a middle school band kid to starring in and producing numerous hit singles, but the Lego documentary glosses over Williams' triumphs and tribulations with surface-level detail.
