A new animated documentary presents the life of musician Pharrell Williams in an enjoyable and surprising Lego package.

The soundtrack is stuffed with hits but you’re not given the chance to settle into any of them. It’s also well stocked with platitudes and you are given plenty of time to mull over these. Too much time.

Piece By Piece’s very existence is baffling, and the Lego of it all is never entirely justified, but as an unconventional documentary of a maverick musician, it works — just about.

It’s an efficient little movie that has plenty of dazzle and charm, even if the more nuanced, less plasticky version of the story stays firmly in the toy-box.
