Writer-director Sadrac González puts an austere, arty spin on a solid science-fiction premise in "Black Hollow Cage," a time-travel movie more in the mold of Andrei Tarkovsky than "Back to the Future." The film looks stunning and presents some provocative ideas, but González's quietly contemplative approach is numbing.
