"The Box" might remind you why you love suspense and hate suspense at the same time. Richard Kelly’s film keeps you in suspense until you are pleading with it to tell you more. But you may hate it because you are wondering if the damn this is ever going to pay off. After awhile you get the sense that Kelly’s film is going to be one of those ambiguous ones, and certainly ambiguity is one of those trademarks a cinephile can enjoy. But the mind-teasing conundrum of this uncommonly weird studio movie teeters dangerously to the point of not wanting it to be so damn ambiguous.
