In the lead, Mbatha-Raw delivers a shaken, exposed performance that hints at the more familiar stories of domestic trauma (drug use, suicide, having to give up a child) that this otherwise super story might stand in for.

Hart and Horowitz's script connects the dots on the meaning and messages of the film, which is thrilling in its radicalism. But the execution is heavy-handed, sapping the joy of discovery from the film packed with so much originality, brilliance and beauty to be discovered.

Mbatha-Raw brings a fierce, quiet containment to the lead role, and Hart builds so much mood through her atmospheric cinematography and deliberately slow pacing that it nearly papers over the sketched-in quality of the script. Eventually, though, you start to wish her characters would speak in more than just vague koans and disaster-movie platitudes.
