Jared Hess's indie sensibilities help to elevate a video game adaptation that is boosted further by Jack Black's irrepressible star turn. The special effects could be better, as could the female roles. But this remains an entertaining fantasy adventure that makes light work of what might appear to be unpromising source material.

Sebastian Hansen, Emma Myers, Danielle Brooks and Jennifer Coolidge also star in the story of four strangers who must find their way back home after being pulled into a cubic wonderland created by a doorknob salesman.
