Anytime you see a film in the New Frontiers category at Sundance, it's a dicey proposition. The category tends to showcase a lot of edgier and experimental films that push the boundaries of filmmaking, and as a result, you never know for sure what you're going to get. Sometimes New Frontier films are intriguing, sometimes puzzling, and occasionally dumbfounding, but they're almost always interesting and a welcome break from the usual fest fare. Sometimes, I'll see a New Frontier film and not be wild about it at the time, but it will linger in my head and make me think long after the typical fest fare has come and gone. Such was the case with Reversion, the second feature directorial effort by Mia Trachinger, whose first film, Bunny, garnered her "Someone to Watch" and "Best Feature under $500,000" nominations at the Indie Spirit awards in 2001.

I caught a public screening of Reversion at the Egyptian near the end of the fest. There were a good many walkouts (though I tend to expect that for New Frontier films, and consider it more a reflection of the diversity and edginess of the category than of the films themselves) but there were far more people who stuck around for the Q&A, and quite a pack who followed Trachinger out of the theater afterward to talk more about her film.
