In China, the cost of automotive injury is often much higher than the cost of killing someone with your car.

The sort-of hero of Old Stone is a straight-shooting taxi driver who loses everything trying to do the right thing after a drunken passenger causes an accident. The contrast between old social nets and the new selfishness provides background here, but young Chinese-Canadian filmmaker Johnny Ma is also a quietly sneaky stylist, moving confidently from a plain documentary feel to darkly comic noir in the flick’s fast-moving 80 minutes. It’s an outstanding debut.
