The star of the film is the story, which unfolds in bits and pieces as memories are recovered before a final twist that radically changes everything.

Radius is a high-concept movie from start to finish, and it relies on surprises to keep the story moving.

The film's budgetary restrictions are apparent throughout and there is some stilted acting but this is intelligent sci fi, a film whose ideas and open-ended questions are more important than its budget.

Radius is absolutely worth checking out, as it'll go down as one of the most intriguing films no one saw this year.
