When director Curry Barker sat down to discuss his breakout horror feature "Obsession" with /Film, he explained why the genre attracted him more than others. "A romance has rules," he told us. "You can't do this, you can't do that, because then it's a horror." Avoiding that escalation is what keeps most filmmakers in safe, neatly categorized boxes, but enthusiastically chasing it has made Barker one of the most promising directors of the year.
