A fascinating and troubling film, unfortunately burdened with the presence of the worst actor alive, Keanu Reeves. Worth seeing, but don’t be surprised if you find yourself cringing whenever his voice is heard. Even rotoscoping can’t save his attempt at a performance. It is even worse when he is onscreen with the accomplished Woody Harrelson and Robert Downey Jr: it’s like you’re suddenly watching Laurel and Hardy and Dick Cheney.
