Sundance is responsible for premiering some of the most influential horror genre pictures in recent years, including <em>Saw</em> and <em>Haute Tension.</em> Well, they've done it again this year with <a href="http://festival.sundance.org/2009/film_events/films/grace"><em>Grace</em></a> a brutally bloody, wickedly sly thriller that functions as an ingenious critique of the <a href="http://www.newyorker.com/arts/critics/books/2008/11/17/081117crbo_books_acocella">phenomenon of overparenting.</a> </p><p>The lovely Jordan Ladd plays a pregnant woman obsessed with organic products and natural birthing processes. When our heroine gives birth to a still born child -- and then mysteriously wills her back to life with her breast milk -- all of her vegan beliefs are violently testing. </p><p>This is some seriously mean-spirited business. (If watching a tiny child being periodically placed in peril isn't your thing, you should definitely stay far away.) But director Paul Solet displays an exacting control over the material; and on more than a few occasions during this low-budget, slightly hysterical story, I gasped in genuine fear. Indeed, I'll never look at a breast milk pump quite the same way again. </p><p><em>Grace</em> just premiered in a Friday night midnight slot, but I have a feeling this one is going to be generatinig buzz throughout the fest.
