The filmmakers formerly known as the Wachowski brothers (The Matrix, Cloud Atlas) are responsible for this madly over-conceptualized, pulp sci-fi doohickey. Mila Kunis is a poor, Chicago house cleaner who finds out the Earth is just an "estate" built and populated by an ancient alien dynasty—and that she's the long-lost queen of the galaxy. The story is a transparent fairy tale about a missing princess in (frequent) need of rescuing and the dashing knight (Channing Tatum) who protects her from her evil royal family. On top of that familiar framework, the Wachowski siblings have added bits of Buck Rogers, Flash Gordon, Dune, The Matrix, Brazil and The Fifth Element. It's entirely ridiculous, but damned if it isn't eye-poppingly pretty and filled with zippy, zappy entertainment.127 minutes PG-13.
