A movie documentary that uses only Lego pieces might seem an unconventional choice. When that documentary is about renowned musician-producer Pharrell Williams, it’s actually sort of on-brand.

“Piece by Piece” is a bright, clever song-filled biopic that pretends it’s a behind-the-scenes documentary using small plastic bricks, angles and curves to celebrate an artist known for his quirky soul. It is deep and surreal and often adorable. Is it high concept or low? Like Williams, it’s a bit of both.
