We’ve sort of seen it before: A guy is driving home for his daughter’s birthday, enters a tunnel, and gets trapped inside. Yet while Kim Seong-hun’s “Tunnel” sounds like it resembles any number of creepy tunnel pics or grand catastrophe epics, it’s actually a lean, enjoyable disaster story with enough distinctive elements to make it feel relatively fresh. Though unlikely to match the success of the director’s earlier “A Hard Day,” it shares with that film a biting critique of Korea’s government, wrapped in the kind of direct, personal drama that climaxes with lump-in-the-throat pay-offs for the emotionally susceptible. Home B.O. earnings after an Aug. 10 opening have been strong, with 1.8 million admissions the first weekend; a targeted stateside release Aug. 26 should see a small but enthusiastic response from Asian action fans.
