Amy Seimetz's directorial debut is a vivid, suspenseful noir set against a sweltering backdrop of a barebones Florida crime saga. "Two-Lane Blacktop" by way of "Bonnie and Clyde," Seimetz's pulpy tale follows lovers Crystal and Leo (perennial character actress Kate Lyn Sheil and microbudget filmmaker Kentucker Audley) on the lam for mysterious reasons only vaguely made clear near the end of the first act, but even then much of the drama remains deeply ambiguous. Sheil's performance, all scowls and muffled shrieks, provides the ideal counterpoint to Audley's muted delivery. From the shock of its opening shot to the tension of its closing moments, "Sun Don't Shine" conveys mood so eloquently that it's easy to get lost in the proceedings without realizing that so little has happened. It's one of the most impressive debut features to come along in years. Criticwire grade: A-I'm really glad to learn about this writer/director and the way she works! An original? Yep! I think so.
